Installation Instruction - ANDELI MCT Series Owner's Manual

5. INSTALLATION INSTRUCTION

The machine is equipped with power voltage compensation device. When the power voltage
fluctuates between±15% of rated voltage, it still can work normally.
When the machine is used with long cables, in order to prevent voltage form going down, bigger
section cable is suggested. If the cable is too long, it may have great affluence on the arc-striking
or other performance of cutting system, e.g. the HF arc-striking performance get weak or the
system work abnormally. So cables of configured length are suggested.
5.1 Make sure intake of the machine is not blocked or covered to avoid malfunction of cooling
system.
5.2 Connect the protective gas source. The gas supply passage shall include a gas cylinder, an
argon gas pressure reducing flowmeter and a gas pipe. The connecting portion of the gas pipe
shall be fastened with a hose clamp or other articles to prevent argon gas leakage and air ingress.
5.3 Ground the cables with section area no less than 6mm 2 to the housing, the way is connecting
screw in the back of the power source to ground device, or make sure ground terminal of power
socket is firmly connected. Both ways can be used for absolute safety.
5.4 According to the input voltage level of the welding machine, connect the power line to the
distribution box of the corresponding voltage level. Do not connect the wrong voltage. Also
ensure that the error of the power supply voltage is within the allowable range.
