CO2 Welding Gun / Torch

The torch assembly consists of conduits to supply the consumable wire electrode and the shielding gas into the welding gun. The torch assembly may also carry hoses for water circulation in the welding gun, to effectively cool it from the heat of the welding arc. The torch assembly also contains a power cable and control cable. The torch assembly is normally 3 to 4.5 metres long and is quite flexible. The shielding gas flows through the annular space between a contact tube and outer nozzle. The outer nozzle prevents air aspiration into the arc zone. The contact tube at the centre of the welding gun guides the consumable wire electrode into the job. It also picks up the current from the positive power cable and passes it on the wire electrode. The welding gun is provided with a switch, which when actuated by the welder allows the flow of the welding current, the consumable wire electrode and the shielding gas.
