A great help in welding processes
Rarely used pure, helium is an inert gas, very light with high ionisation potential which allows to work with extreme welding parameters.
Normally used in mixture with Argon and other active gases, it increases the heat input on the process allowing to increase the productivity and the protection of the welding bath.
Suitable for all electric arc welding processes (TIG / MIG / MAG) but also plasma and laser, in particular on materials such as aluminium and copper that quickly disperse heat.
