DCEP. DCNP: welding holder connected to “-“and work piece to “+”; DCEP: workpiece to “-“and welding
holder to “+”. Please choose the proper connection method according to different workpiece and
processing methods. Unstable arc, spatter, and electrode sticking could happen if improper polarity is
selected. Please change the polarity by exchanging the quick connector in case of above abnormal
situation.
3) When switching the welding mode to MMA, welding can be carried out with output current in rated
range.
4) Select cable with larger cross-section to reduce the voltage drop if the workpiece is far away from the
welder with long secondary cables (welding cable and earth cable).
Preset the welding current according to the type and size of the electrode, clamp the electrode and then
welding can be carried out by short circuit arc ignition. For welding parameters, please refer to 10.3
table.

10.4 Installation and operation for MIG welding
Installation
1) Insert the torch into EURO Connector for Torch in MIG on the front panel and tighten it.
2) Connect the cylinder equipped with the gas regulator to the gas inlet on the rear panel of the
machine with a gas hose.
3) Insert the cable plug with work clamp into the “-” output terminal on the front panel of the welding
machine, and tighten it clockwise.
4) Insert the quick plug on the front panel into the “+” output terminal and tighten it clockwise.
5) Install the wire spool on the spindle adapter. Make sure that the groove size of wire feed roll
matches the contact tip size of the welding torch and the wire diameter being used. Release the
pressure arm of the wire feeder to thread the wire through the liner, into the roll groove and then into the
liner of central connector. Adjust the pressure arm to ensure no sliding of the wire. Too high pressure
will lead to wire distortion, which will affect wire feeding. Press the Inching button to thread the wire out
of the contact tip on the torch.Sketch map of installation
