INSTALLATION INSTRUCTION
The welding equipment is equipped with power voltage compensation device. It keeps the machine work normally when
power voltage fluctuating ±15% of rated voltage.
When using long cable, in order to reduce voltage drop, big section cable is suggested. If the cable is too long, it will
affect the performance of arcing and other system function, it is suggested to use the recommend length.
1. Make sure the intake of the machine is not covered or blocked to avoid the malfunction of the cooling system.
2. Use ground cable whose section no less than 6mm
2
to connect the housing and earth. The method is to connect the
grounded interface in the back to the earth device, or make sure the earth end of power interface has been reliably
and independently grounded. Both ways can be used together for better security.

、
Correct Installation of MIG
:
1) Connect the gas cylinder with CO2 decompression flow mete tightly to CO2 mouth behind the machine via air tube.
2) Insert the swift plug of earth cable into socket at the front panel.
3) Set the wire wheel with wire on the wheel axis, the wheel hole should be matched with the wheel fixer.
4) Choose wire slot according to wire size.
5) Loosen the screw of wire-pressing wheel, pit the wire into slot via wire-lead tube, adjust the wire-pressing wheel to
keep wire fix from gliding, but strength should be suitable in case the wire distorts and affects wire sending.
6) Wire roll should turn clockwise rotation to let out wire, to prevent wire from gliding; wire is usually set to the fixed hole
on the wheel side. To prevent the bent wire from getting stuck, please cut off this part of the wire.
7) Put and tighten the torch on the output socket and put the wire into the torch by hand.

Correct Installation of LIFT TIG
:
1)
Connect the shielded-gas source correctly. The gas supplying route shall include gas cylinder, argon decompression
flow meter and gas pipe. The connecting parts of the gas pipe should be fastened by hose clamp or other objects, in
order to prevent leakage and air-in.
2)
Connect the plug of TIG torch to “-“of the front panel, and fasten it clockwise.
3)
Connect the plug of TIG torch to the relative interfaces of panel and fasten the screw.
4)
Connect one end of the earth clamp cable to “+” of the front panel, and fasten it clockwise, the other end clamp the
workpiece.
