What is an Arc Welding Torch in Welding?

An arc welding torch is a device that is used to transfer current to a fixed welding electrode. The torch also serves to position the electrode and direct the flow of shielding gas.

What is a welding torch used for?

The most common type of arc welding torch is the TIG (tungsten inert gas) torch. This type of torch is often used for welding aluminum and stainless steel. The TIG torch has a tungsten electrode that is non-consumable. This means that the electrode does not melt during the welding process.

The TIG torch also has a gas cup that surrounds the electrode. This cup helps to shield the weld area from atmospheric contamination.

Another type of arc welding torch is the MIG (metal inert gas) torch. This torch is often used for welding mild steel and aluminum. The MIG torch has a consumable electrode that is made of copper or steel. The electrode melts during the welding process and becomes part of the weld pool.

What is the difference between arc and gas welding?

The main difference between arc and gas welding is that, in arc welding, an electric arc is used to create heat while, in gas welding, a flame is used to create heat.

Welding torch function

The welding torch has 3 main functions:

The welding torch transfers current to the electrode.
The welding torch positions the electrode.
The welding torch directs the flow of shielding gas.

Welding torch price

The price of a welding torch depends on the type of torch and the brand. A TIG torch can cost anywhere from $100 to $1,000 while a MIG torch can cost anywhere from $50 to $500.
