5. Connect Earth Clamp (22) to the work piece. Contact with workpiece must be strong contact with clean,
bare metal, with no corrosion, paint or scale at the contact point.
6. Connect the gas regulator (optional) and gas line to the inlet on the rear panel (11). If the regulator is
equipped with a flow gauge, the flow should be set between 8 – 15 L/minute depending on application. If gas
regulator is not equipped with a flow gauge, adjust pressure so gas can just be heard coming out of the torch
conical nozzle (24). It is recommended that gas flow is checked again, just prior to starting weld This
can be done by triggering the MIG torch with the unit powered up.

hose, which come from the wire feeder to the copper nozzle of gas bottle. The gas supply system includes
the gas bottle, the air regulator and the gas hose, the heater cable should be inserted into the socket of machine’s back,
and use the hose clamp to tighten it to prevent leaking or air-in, so that the welding spot is protected.
Please note:
1. Leakage of shielding gas affects the performance of arc welding.
2. Avoid the sun shine on the gas cylinder to eliminate the possible explosion of gas cylinder due to the
increasing pressure of gas resulted from the heat.
3. Ensure no person is up against the regulator, before the gas release or shut the gas output.
4. The gas output volume meter should be installed vertically to ensure the precisely measuring.
5. Before the installation of gas regulator, release and shut the gas for several time in order to remove the
possible dust on the sieve to avail the gas output.
