tIg-welding

Clearing the station before welding.
The TIG-welding is very sensitive about the surface (which is to be welded) contami-
nation. For this reason, before welding you have to remove rests of paints and greases
as well as the oxidized layer from the surface which will be welded.
DC tIg-welding
• Connect the gas hose to the gas to welder supply socket.
• Connect the gas hose to the welding gun and to the argon supply
(to the gun) socket.
• Connect weld piece to the mass clamp in welder, outlet (+).
• Connect the welding handle plug to the arc and argon control rod.
gas test: Check the connection of the electric supply and switch on the voltage.
Open the valve (regulator) of bottle with argon and switch on flow meter. Gun
switch-key has to be pressed and you have to select an appropriate gas flow. The
inflow switch-key has to be released and the gas inflow will be automatically stopped
after several seconds. In case of using the high frequency ignition, the wolframic elec-
trode has to be retracted 2-3 mm from the weld piece. Next, after switching on the
switch-key, the arc will be triggered.
The switch off will result in the reduction of electric current intensity and the arc will
no longer be active. The blowing shaft can not decay before the electric arc switch off.
Gas must cool down the fusion weld as it will not become oxidized. After finishing
the welding process, you have to switch off the argon supply button on the bottle and
the welder supply. Pulling the electric supply plug when the electric supply switch is
on is prohibited.
