Argon arc welding machines ESAB OrigoTig, BuddyTig, etc.

An argon welding machine is an inverter connected to a 220 or 380 V network, which converts the current from alternating to direct several times, while increasing its frequency. Inside, several transformers, diode bridges and a key board are used. All this contributes to a light weight of 4-30 kg and high quality of the seam.

If you need a welding machine in the garage, then choose the 220 V model. For production, 380 V is optimal. The weight of 4-8 kg is useful when traveling and working at height, as well as with three-dimensional structures. With stationary use, weight does not matter.

The TIG method has clear advantages over other welding methods, but working with an argon welding machine also has several disadvantages that you need to be prepared for when choosing this welding method.

Advantages of the TIG method

• local heating eliminates serious deformations of the product;
• a thin tungsten needle allows you to create narrow, neat seams;
• it is possible to weld with and without an additive, affecting the height of the roller;
• the compound is obtained without a slag crust on top;
• in most cases, no follow-up is required.
• mechanical processing;
• stainless steels and non-ferrous metals can be welded;
• the seams are sealed and withstand high pressure;
• there are no splashes of metal sticking to the surface.

Disadvantages of the TIG method

• connection speed is inferior to MIG;
• the burner hood interferes with work in hard-to-reach places;
• the ceramic nozzle slightly limits the visibility of the welding bath;
• the quality of the seam depends on the user's skills (it will not work immediately to take and cook like a semi-automatic machine);
• it is required to constantly feed the additive with the second hand and control its length (during welding, the length of the wire is rapidly reduced, and long pieces are inconvenient to hold in your hands,
• because they "walk");
• tungsten electrodes are more expensive than coated ones;
• additional costs for argon;
• it is impossible to weld parts efficiently on the street in a strong wind (argon is blown away and the welding bath remains unprotected).
