terminal between wire feeder and wire spool; When use solid wire with gas protection, torch
socket should be connected to the positive output terminal, ground cable should be connected to
the negative output terminal; When use flux-cored wire, the ground cable should be connected to
positive terminal.
3.4 Welding environment and safety

Working surrounding
a) Welding should be carried out in dry surroundings. The air humidity level should not be higher
than 90%.
b) The temperature should be between -10

C to 40

C.
c) Don’t use the welding machines in sunshine or rain. Keep it off water.
d) Don't use the machines in the places of dust or corrosive air.
e) MIG welding should not be carried out in places with quick air flow.

Safety norms
Protection circuit of over-voltage, over-current and over-heat circuits are designed in the welding
machines. It will stop working automatically when the input voltage, output current or internal
temperature exceed the rated value. But if the machines are excessively used, such as with input
voltage higher than the rated, the machine might be damage. Please pay close attention to the
following matters.
a) Keep good ventilation!
The welding machines work with high welding current. Nature air flow can’t reach the requirement
of heat dissipation. So the fans are installed as cooling system to ensure stable performance.
Make sure the ventilation windows are not covered or blocked. The distance between the
machines and things around should not be less than 0.3m. Good ventilation is good for welding
performance and operational life.
b) Never over load!
Check the maximum rated current (according to the Duty Cycle chosen). Make sure the welding
current is never higher than the rated value. Over current running will obviously shorten the
operation life, even damage the machine.
c) Never over voltage!
The Input Voltage could be found in Technical data diagram. The auto-compensation function
will keep the welding current in the rated range. If the input voltage exceed the permissible value,
the machine would be damaged. Users should take protective measures in advance to avoid it.
d) Make sure earth connected before operation.
