6. INSTALATION AND OPERATION

Note: - Please install the machine strictly according to the following steps.
- Turn off the power supply switch before any electric connection operation.
- The protection class of this machine is IP21S, so avoid using it in rain.
6.1 Connection of input cable
1) A primary power supply cable is available for this welding machine. Connect the power supply cable to the rated
input power. (Ground connection is needed for safety purpose.)
2) The primary cable should be tightly connected to the correct socket to avoid oxidization.
3) Check whether the voltage value varies in acceptable range with a multi-meter.
6.2 MMA installation
1) Two quick plugs are available for this welding machine. Insert the quick plugs into the quick sockets on the front
panel of the machine, and tighten them to ensure good contact. Otherwise, the plugs and sockets will be burned if
the working time is long and the working current is high.
2) Insert the cable plug with electrode holder into the "＋" socket on the front panel of the welding machine, and
tighten it clockwise. Insert the cable plug with work clamp into the "－" socket on the front panel of the welding
machine, and tighten it clockwise.
3) Generally, DCEP connection and DCEN connection are available in MMA.
DCEP: Connect the electrode holder to "＋" output terminal, and the work clamp to "－" output terminal.
DCEN: Connect the electrode holder to "－" output terminal, and the work clamp to "＋" output terminal.
Operators may choose DCEP/DCEN according to workpiece and electrode application requirement. Phenomena
such as unstable arc, excessive spatter, and electrode sticking will occur when improper polarity is selected.
Change the connection by exchanging the fast plugs to solve the problem.
4) Select cable with larger cross-section to reduce the voltage drop if the secondary cables (welding cable and
earth cable) are long.
