OPERATION

TIG Welding Function
1) While this welding & cutting equipment is operated, the power supply indicator is on, and
the built-in fan will function.
2) Switch to the TIG welding function mode.
3) Press the gas release button and modulate the volume of gas output to the required
value.
4) Press the button on the welding torch and the electromagnetic valve will function. The
sound of releasing electricity is audible and there is gas coming out of the welding torch.
Please note: Before the initial welding operation, press the button on the welding torch for
several seconds in order to remove the gas inside the gas tub, and the welding operation is
accessible. There is gas output within a few seconds after the welding operation, that is a
special design to protect the welding point before it cools down. Therefore, after the arc is
gone, maintain the welding position until the heat produced during the welding operation
dissipates.
5) The welding current output is adjustable, according to the thickness of the welding material
and required craftsmanship.
6) Maintain a distance of 1-4mm between the tungsten electrode and the work piece. Press
the button on the welding torch. HF electricity will release between the welding electrode
and the work piece. After the arc starts, the splash of the HF arc will vanish and the welding
operation can begin.
