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).
One/two gas cylinders can be mounted on the bottle carrier
on the back of the trolley.
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.
