OPERATION
-11-
If transformer is over-heat, the heat relay inside it will open and will output an instruction to
circuit board, cut AC relay and the output welding current, and brighten the over-heat pilot lamp
in the front panel. At this time, the machine should be relaxed for 15 minutes to cool the fan.
When operating the machine again, the welding output current or the duty cycle should be
reduced.
§3.3 Equipment Connection
Operation Steps
：
1. Connect the power cable of welding machine with the output switch in electric box on the spot.
2. Connect the cable of wire feeder with the positive output of welding machine.
3. Connect the control cable of wire feeder with the aero socket on the front panel of welding machine.
4.Connect the negative output of welding machine with the workpiece (base metal).
5.Connect the heating power cable of gas cylinder to the 36V or 24V gas heating power socket on the rear panel
of welding machine.
6.Connect the output pipe of gas cylinder with the input of valve on the wire feeder.
7.Plug the joint of welding gun into the output of wire feeder. The welding wire should be aimed at the wire-in
port.
Note: The plane of the joint should aimed at screw, plugged tightly and rotated 90º, then screw the bolt tightly to
ensure the gun contacting closely.
