Comparison Eltos PPT-1800 vs Dremel VersaFlame

— Contact. It is customary to call contact soldering irons not all soldering irons, in which the tip touches the material during operation, but only models in which the operating temperature is maintained constantly (unlike impulse ones — see below). This format is suitable for most soldering jobs, and contact soldering irons themselves are available in a wide variety of capacities — from a few watts (for soldering microcircuits) to several hundred watts (for soldering dishes, etc.). Also, the advantages of such a tool are the simplicity of design and low cost. On the other hand, continuous heating can create problems when soldering heat sensitive components.

— Pulse. The name of this type comes from the format of operation: heating does not occur constantly, but in pulses, at the user's command. The classic pulse soldering iron has a pistol grip and a start button for the index finger. When you press this button, the sting very quickly warms up to operating temperature, and when released, it cools down. Pulse soldering irons are indispensable for delicate work, where you need to accurately dose the amount of heat supplied to the soldering point. At the same time, high power (required for fast heating) allows them to be used for larger tasks. The main disadvantage of such instruments, in comparison with classical contact instruments, is their higher cost.

— Contactless. Soldering irons capable of working without direct contact with the material. This method of operation is found exclusively in gas models. For more information about them, see "Nutrition"; here we note that non-contact soldering is characterized by high operating temperatures and provides some features that are not available for a contact tool. For example, it allows you to warm up and melt a rubber tube attached to a wire for insulation (whereas rubber would stick to a regular tip). At the same time, many non-contact models are equipped with nozzles that allow you to work in a contact way.

— Soldering Station . The most advanced version, consisting of the soldering iron itself and an additional unit through which the tool is connected to the network. The additional unit has various advanced control options — smooth temperature control, a digital display for controlling operating modes, etc.; in addition, it houses a stand for a soldering iron and other additional accessories such as a cleaning sponge, trays for consumables, etc. This greatly expands the possibilities of soldering and simplifies the work, allowing you to cope even with professional tasks. The type of the soldering iron itself in the station can be anything, however, classic contact tools are most often used. At the same time, they are often made low-voltage, which reduces the level of electromagnetic interference and makes it easier to work with sensitive radio components.

— For plastic pipes. A specialized type of soldering iron, designed, in accordance with the name, for welding pipes made of polypropylene and other similar plastics. Such models are noticeably different in design from other types described above: they do not use a thin sting, but cylindrical nozzles of different diameters, for different pipe sizes (for more details, see "Nozzles included"). In addition, "pipe" soldering irons have high power — otherwise it would be impossible to ensure efficient heating of the pipe, especially of large diameter. Note that a technically similar tool can also be used for soldering thick wires.

— Ensiform. Sword-shaped are specialized devices for soldering polypropylene pipes. Structurally, they consist of a stable stand and a body with a handle, to which a heating element is attached in the form of a wide sword blade. Although, in truth, the heater is more like the soleplate of an iron. The temperature from the heating plate is transferred to solder nozzles of a standard size grid for different diameters of the outer pipe shell. Models of this form factor are usually designed for stationary work.

— U-shaped. Soldering irons for manual welding of plastic pipes and fittings by heating their joints. The shape of the heater for U-type devices allows soldering work in the corners of rooms, close to walls or floors.

— Cylindrical. Devices with a heating element in the form of a cylinder, to which nozzles for a specific pipe diameter are pressed with bolts. Cylindrical devices are designed to perform work on soldering polypropylene pipes in cramped conditions and in the case of complex wiring of communications. The case of such soldering irons continues the cylindrical shape of the heater, and due to its compactness, the device easily penetrates into hard-to-reach places.

— Tweezers. Thermal tweezers have found application for mounting or removing electronic circuit components and miniature radio components f...rom printed circuit boards. With two interlocking stings, they melt the solder near the required element, tenaciously grab the part and take it out of their homes. They got their name because of the similarity with traditional tweezers.

— hatchets. Soldering irons with a large flat tip in the form of a wedge attached to a handle made of heat-resistant material in the image and likeness of an ax handle. The wide tip creates a large area of contact between the mating parts for efficient heat transfer and a strong bond. Soldering hatchets are used in tin work: when repairing dishes, soldering leaky barrels, heating radiators, etc.

— Pistols. This version of the soldering iron assumes the presence of a pistol grip located at a right or close to it angle to the body. A heater is used as a “muzzle” for such devices. The pistol grip allows you to comfortably hold the device during operation and control the heating process of the soldering iron by pressing the trigger.

- Network. Power from the mains - most often the usual household at 230 V, however, there are also "car" models at 12 V, with a connection to the cigarette lighter socket. This option is well suited for all types of soldering irons (except perhaps non-contact ones), it allows you to create a tool of almost any power with unlimited operating time. The main disadvantages of network models are the need for an outlet nearby, as well as the presence of a wire that limits mobility and, if handled carelessly, can get under the sting.

- USB port. Powered from the USB port is implemented in compact soldering irons of relatively low power used for small volumes of simple soldering. The advantage of such models over peers is the ability to work in the field due to the provision of energy supply from a laptop or power bank.

- Gas. Soldering irons that work by burning gas are, in fact, burners with advanced features. Gas enters the burner from a built-in reservoir, which in most models can be filled from a simple cartridge (similar to lighters). The key advantages of a gas tool are high power, the ability to reach high operating temperatures - more than 1000 ° C - and suitability for non-contact soldering (see "Type"). In addition, such soldering irons are autonomous and absolutely independent of the power supply. Among their disadvantages, one can note the difficu...lty in handling and maintenance, due, in particular, to the presence of an open flame and the need to comply with relevant safety regulations.

- Battery. The power supply from the built-in battery makes the soldering iron self-contained and allows you to use it regardless of whether there are outlets nearby. And the absence of a network cable has a positive effect on the convenience of work. On the other hand, battery power is suitable only for the least powerful models - usually up to 10 W, the tool itself, all other things being equal, turns out to be noticeably heavier and more expensive than the mains one, its operation time is limited, and when the charge is exhausted, the outlet will still be needed.

- Batteries. Models powered by replaceable AA batteries and some of its derivatives. Due to their low power, such devices should not be considered as the main tools for performing soldering work. However, they are great for when you need to solder something away from a stationary power supply.

— Plastic. Plastic holders are quite light, but they get very hot during long intense loads, which interferes with the further soldering process. Soldering irons with a plastic handle are usually used in household and small cycle work.

— Wood. Devices with a wooden handle have excellent thermal insulation properties and are sharpened for any task. Effective protection against overheating is the main strong point of soldering irons with wooden holders.

Rated power of the soldering iron; in models with adjustments (see below) — the maximum rated power. The more powerful the tool, the more intense the heat it provides, the better it is for working with large objects, such as soldering thick wires, repairing radiators, etc. However, excess power is just as undesirable as insufficient: a tool that is too “weak” will not achieve normal soldering quality, and a tool that is too “strong” will overheat the parts to be joined and may damage them (not to mention excessive power consumption). Therefore, you need to choose a soldering iron in terms of power, taking into account the work for which it is planned to be used.

So, low-power models up to 10 W are intended mainly for miniature parts and delicate work — like soldering microcircuits. The best option for domestic use is 25 – 35 W; for large elements, you can use more powerful models, up to 50 W ; these same indicators will suit most radio amateurs. Soldering irons for 50 – 100 W are designed mainly for thick wires, found, for example, in the on-board networks of cars; and high power is typical for a tool designed for large structures: metal containers (pots, buckets, etc.), radiators of the same cars, etc.

A separate case are models for soldering plastic pipes (see "Type"): they give out at least 700 W, and in the most powerful models, the figures can exceed 2 kW. Here, the more powerful the...tool is, the larger the pipes with which it can work: for example, 700 – 800 W is enough for parts with a diameter of 20 – 25 mm, and for 63 mm pipes it will take no less than the mentioned 2 kW.

Some soldering irons have power controls (see below) that allow you to adjust them to a particular situation and expand the possibilities of application.

Note that high power in itself does not mean a high operating temperature — it only facilitates and accelerates heating.

The highest temperature to which the soldering iron can heat the material being processed. This temperature should be high enough to melt the solder or other workpiece material (such as polypropylene in soldered pipes), but not too high so as not to overheat the joint. Therefore, the choice for this indicator depends on the features of the planned work.

Note that in most household soldering irons for 20 – 60 W, the maximum temperature varies between 300 – 400 °C — this is enough to work with most solders used in radio engineering. In more powerful contact models, as well as soldering stations (see "Type"), there are indicators of the order of 700 – 800 °C — this allows you to work without problems with refractory solders, the melting point of which starts from 450 °C. For models designed for plastic pipes, the standard indicator is 300 °C — it is this temperature (or slightly lower, about 280 °C) that is considered optimal for soldering polypropylene. And the highest temperatures — 1300 °C and more — are able to provide gas soldering irons (see "Power")

The amount of time in minutes required for a soldering iron to warm up a tip or other actuator to operating temperature. The shorter the heating time, the faster the device can begin soldering work.

— Two power levels. Soldering irons capable of operating at two power settings — reduced and full. Features of such work depend on the type of soldering iron. For example, in contact models of medium power (up to 60 W), the standard mode is usually full power, while reduced power is used for individual delicate work. But in soldering irons for plastic pipes, which have high power, most of the work is carried out at a low intensity, while the “full” tool is turned on only when working with large diameters. For a number of reasons, it makes no sense to use more than two power levels in soldering irons — in particular, it is easier to fine-tune the operating mode by adjusting the temperature.

- The number of nozzles. The total number of working attachments supplied with the tool. The abundance of nozzles allows you to use the soldering iron for various types of work. At the same time, the more nozzles in the kit, the more noticeable this parameter affects the cost of the kit. When choosing, you need to proceed from how important the variety of possibilities is - so as not to overpay for extra attachments that turned out to be useless in practice.

- Nozzle diameter. It is customary to indicate the working diameter of complete nozzles for soldering irons of plastic pipes. This parameter corresponds to the diameter of the pipes. For the installation of domestic heating and water supply systems, nozzles with a diameter of 16, 20 and 25 mm are usually used, for risers - 32, 40 or 50 mm, for heating systems without forced circulation of the coolant - 63 or 75 mm, for sewerage and the construction of industrial highways - 90, 110 or 125 mm.

- Stand. Traditionally, they are made of heat-resistant materials - so that they can safely hold a heated soldering iron. You can also assemble a similar design yourself (or adapt some more or less suitable object under the stand); however, regular coasters are usually more convenient and safer than improvised ones.

- Pipe cutter. As the name suggests, a pipe cutter is a tool for cutting plastic pipes and other similar parts. Accord...ingly, only soldering irons designed for plastic pipes are equipped with such a tool. A pipe cutter can be purchased separately, but buying it together with a soldering iron is often more convenient, if not cheaper.

- Cap. Protective cap for the soldering iron tip or its entire heating rod. It is put on for the period of storage or transportation of the device in order to avoid damage to the working body or heater.

- Flux (rosin). The general purpose of all fluxes is to improve the efficiency of solder "setting" when soldering. Such compositions perform several functions at once: they remove oxides and slags from the surface of the parts to be joined, prevent the formation of new oxidations, promote the spreading of liquid solder and more dense wetting of parts with it.

As for rosin, this is one of the most famous and common fluxes used in hand soldering. Rosin is extracted from the resin of coniferous trees, it is quite easy to obtain, and also safe to use. This type of flux can be used in both solid and liquid form. Molten rosin removes oxide films well on the surface of most metals, but it is poorly suited for heavily contaminated surfaces.

- Solder. The main "consumable" for soldering, which is responsible for the direct connection of parts to each other. The molten solder adheres tightly to the parts, fills the gap between them and, when solidified, creates a strong connection. The composition and specialization of the solder can be different: there are solders from a low-melting alloy based on lead and / or tin for manual work with metals, from all kinds of oxides for soldering metals and non-metals, etc. Solder is available in various forms - thin wire, rods, pastes, powders, suspensions. Some formulations immediately include rosin, so working with them does not require the use of separate fluxes.

- Sponge. The presence in the delivery set of the soldering iron of a special sponge for cleaning the tip from all kinds of deposits: flux residues, solder, etc. Cellulose sponges are widely used, porous viscose sponges and metal shavings are slightly less common. However, the last option is already the item of a completely different conversation (see the “Tip Cleaner” paragraph).

- Desoldering pump. A separate device in addition to a soldering iron for removing molten solder from the legs of radio components and the surface of printed circuit boards. The desoldering pump is almost indispensable when dismantling multi-output elements, its use ensures accurate soldering due to the quick removal of excess consumables, at the same time, the tool eliminates short circuits between adjacent outputs of discrete radio components when they are heaped on the board. According to the principle of operation, most desoldering pumps resemble a standard syringe with a cylindrical body, a piston and a spring - the solder is sucked through the nozzle due to the vacuum created inside the body when the spring is charged.

- Tip cleaner. As a rule, non-abrasive brass shavings are used as a tip cleaner from solder residues, fluxes and oxides, which is suitable for most types of soldering irons. The cleaning of the working body from all kinds of deposits occurs without a significant drop in the temperature of the tip, which is what sponges do (see the corresponding paragraph).

- Screwdriver. Some sets of equipment for soldering propylene pipes are equipped with a screwdriver. The tool is provided as an auxiliary device for performing soldering work.

- Roulette. “Measure seven times, cut once” - to measure the parameters of plastic pipes being connected, advanced sets of appropriate soldering irons often include a tape measure from 2 to 5 m long. This is quite enough for most cases, while the weight and dimensions of the tape measure body remain small and allow convenient to take measurements.

- Gloves. Gloves made of heat-resistant material are used to protect the user's hands when performing work related to soldering polypropylene pipes. Other types of soldering equipment are not supplied with gloves.

- Bubble level. In the expanded configuration, separate copies of soldering irons for plastic pipes are supplied with a bubble level. This fixture is designed to check the horizontal or vertical position of pipes and other profiles.

- Battery. The presence of a battery in the delivery of battery-powered soldering irons. Eliminates the need to purchase batteries separately.

- Without battery. Battery models that do not come with a rechargeable battery. This solution is beneficial when buying a soldering iron in addition to existing devices of the same brand on a similar battery platform.

- Case (bag). The case in this case is a hard case-container designed for storing and transporting the tool. This case performs two main tasks. The first is the protection of the contents from contact with surrounding objects (in the case of soldering irons, it is primarily about protecting external objects from damage and contamination, and not the contents of the case). The second task of the cases is to keep the tool and all the accessories for it in one place. For all this, improvised cases can also be used, however regular cases are often more convenient and practical. For example, some of these containers are made of heat-resistant and heat-dissipating materials and allow even a hot soldering iron to be placed in them - this can come in handy in case of lack of time. And so that the contents do not hang around the internal volume, the case often provides “seats” for all items placed in it - cells or fasteners. Bags are a rag option for storing tools. Naturally, it is less reliable, but cheaper.
