• Connect the MIG Torch Euro Connector to the torch socket on the
front of the welder . Secure by firmly hand tightening the threaded
collar on the MIG Torch Euro Connector clockwise.
• Check that the correct gas shielded wire, matching drive roller
and welding tip are fitted
• Connect Polar conversion line to the positive (+) welding output
terminal

Connect Earth Lead Quick Connector to the negative (-) output
welding terminal .
• Connect Earth Clamp to the work piece. Contact with work-piece
must be strong contact with clean, bare metal, with no corrosion,
paint or scale at the contact point.

Connect the gas regulator (optional) and gas line to the inlet on the
rear panel . 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 . 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.
