Why should the torch be as cool as possible?
The reason of the torch be as cool as possible.
Welding torch- Welding torch is a type of electrode holding device in which hoses and pipes are connected for the passage of gas and coolant. The main purpose of using welding torch is to weld the metals for the welding. Welding torch is used in Gas tungsten arc welding process for welding.
The below figure represent the schematic diagram of the welding torch.

Gas tungsten arc welding- In Gas tungsten arc welding process, a non-consumable electrode (tungsten) is used for the arc generation. The melting of the electrode does not take place in this process, although the melting of metal takes place at the spot where the arc impacts its surface...
