Argon welding with his hands - the equipment and procedures of

In life there are different situations, when you have something to build or repair.This is especially true owners of private houses, in which to "courtyard" there is always what to do.We often deal with bonding (connection) of the metal, so rarely does without the welding machine.

But Welding - strife.Moreover, it is not necessary to be confused with the soldering, tinning, and the like.Feature works with colored metals and alloys (eg, copper, aluminum, bronze) and stainless steel "stainless" is that conventional welding machine (whether gas or electric) is not appropriate here.

Before consider argon welding, is to figure out what it is.In general - it's somewhere between the above views.Like features are the use of the gas and the presence of the resulting arc.But the principle of action is somewhat different.Namely the need to use an inert gas (argon) is caused by the fact that at high temperatures and alloy steels tsvetmetally interact with "O2" and other gases to form oxides, and some are ignited (lit).For example, aluminum.

Schematic diagram of argon welding

applied electrodes are divided into the melting and non-consumable (tungsten).Argon arc welding is either automatic (either electrode), or manual (non-consumable electrode).However, the "craftsmen" make and semiautomatic machines, although their potential is clearly limited.very different "parts" used for the manufacture of "models".The only thing to consider - the simpler, more reliable and cheaper.Consider one of the options.

What is needed for welding

Transformer .Its capacity is selected depending on what you need to "cook."One of the secondary windings must be calculated on the VAC (65 - 70) with no load.Recommendations for self-selection "iron" and winding coils are not clear to everyone, especially since the manufacturer requires a certain experience itself.It is better to use a ready-made transformer, designed for high amperage (eg, electric "svarochnika").

should be collected and the rectifier, because it uses a constant voltage.Incidentally, the polarity plays a role and can be varied.

burner .Please choose a collet (clamping device) under Ǿ about 2 mm.The other side of the clamp, the holder, soldered copper tube through which gas will be supplied (argon) and the voltage on the electrode.Its diameter of about 6 mm.Solder used high temperature.

to the other side of the collet mounted pipe work (ceramics, quartz glass).It must be easily removable to reinstall the wire.Its diameter is chosen in the range 8 - 10 mm, and length - 50. Inside the electrode is a curved arc, which is held clamping mechanism.By tube argon will be supplied to the workspace.

Assembly "Machine»

carrier tube wrapped with insulating material (fiberglass), above - a second insulating layer.Between them - sealant (silicone).It turns out the similarity of the handle of a revolver.It fastens the microswitch, which will control the operation of the gas valve.

It should be remembered that the flames in the work area should disappear immediately, but after some time.For this industrial model for argon welding provides off-delay.But in practice it is an electronic device only complicates the circuit, so this caveat should be taken into account and disable done manually, with a delay.

This is one of the most cost options.Especially when you consider how much to pay for an industrial machine that is not used on a daily basis in the daily life.For reference: the very tank of gas cost about 1000 rubles, and one refueling - about 300. It will be enough for a lot of work.

Some sources indicate that it is possible to use not only the argon.This is not true.Practice shows that the content of less than 99% makes the welding of poor quality.
