Installation
Equipment is equipped with power voltage compensation equipment. When power voltage fluctuates
between ±15%, of rated voltage, it still can work normally.
When use long cable, in order to prevent voltage form going down, bigger section cable is
suggested. If cable is too long, it may affect the performance of the power system. So cables of
configured length are suggested.
⚫ Make sure intake of the machine not blocked or covered, lest cooling system could not work.
⚫ Make good connection of shielded gas source. Gas supply passage includes cylinder, argon
decompress flow meter and pipe. Connecting part of pipe should use hoop or other things to
fasten, lest argon leaks out and air gets in.
⚫ Ground the earth wire in the power supply cable.
⚫ Correctly connect the arc torch or holder according to the sketch. When use MMA welding:
Make sure the cable, holder and fastening plug have been connected with the ground. Put the
fastening plug into the fastening socket at the “-” terminal and fasten it clockwise. When use
TIG welding: Put the gas-electricity plug of the welding gun to the joint at the front panel, and
fasten clockwise. Put the air switch on the gun to the relevant joint at the front panel, and fasten
the screw.
⚫ Put the fastening plug of the cable to fastening socket of “+” terminal at the front panel, fasten it
clockwise, and the earth clamp at the other terminal clamps the work piece.
⚫ According to input voltage grade, connect power cable with power supply box of relevant
voltage grade. Make sure there is no mistake and the voltage of power supply does not exceed
permission range. After the above job，installation is finished and welding is available.
Before connecting operation please make sure all the power is turned off. The right order is
to connect the welding cable and ground cable to the machine first, and make sure they are
firmly connected and then put the power plug to the power source.
