Connection of shielding gas
Connect the gas hose, which branches off from the back panel
of the welding machine (3), to a gas supply with pressure
regulator (2-6 bar). (Note: Some types of pressure regulators
require an output pressure of more than 2 bar to function
optimally).

cables, good electric contact is required
when connecting earth cables and welding
hoses to the machine.
