shielding gas
The shielding gas used for steel wires is carbon dioxide or a mixture of argon
and carbon dioxide which replaces air in the arc's area. Shielding gas for
stainless steel wires is a mixture of argon and carbon dioxide (2 %) and argon
for aluminium wires. Thickness of the welded sheet and welding power
define the flow rate of the shielding gas.
The machine is delivered with a 4.5 m long shielding gas hose. Connect the
bayonet socket of the shielding gas hose to the machine's hose connector
and the hose connector end to the gas bottle's control valve.
