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). Press the torch gas hose into the gas
connecting branch (4) at the front of the machine.
Important!
In order to avoid destruction
of plugs and cables, good
electric contact is required
when connecting earth cables
and welding hoses to the
machine.
