INSTALLATION INSTRUCTION
1. Make good connection of shielded gas source. Gas supply passage includes cylinder, argon decompressing
flow meter and pipe. Connecting part of pipe should use hoop or other things to fasten, in case lest argon
leaks out and air gets in.
2. Ground the cables with section area no less than 6mm
2
to the housing. The way is connecting screw at the
back of the power source to ground device or making sure connection of AC outlet have already reliably and
separately connected ground. The above mentioned 2 ways can be used at the same time for ensuring safety.
3. Correctly connect the arc torch or holder according to the sketch. When using 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.
4. Put the fasten plug of the cable to fasten socket of “+” terminal at the front panel and fasten it clockwise then
the earth clamp at the other terminal clamps the work piece.
5. 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.
