Note:

1) In order to reduce the working temperature of the machine, it is normal for the fan to continue to rotate for a

few seconds after the power is turned off.

2) In the process of high-strength continuous welding, machine protection may occur, and the OC light on the

machine panel will be on. After continuous heat dissipation, the machine will return to normal, which is normal.

3) During the welding process, if you feel that the welding is not good, the spatter is too large, or the arc is

broken, please exchange the connection of the welding clamp and the grounding clamp with the machine.

Attached table: Self-examination of abnormal conditions without response when turning on the machine:

1. The machine's power switch is not turned on.

2. The power input voltage is wrong.

3. The power plug is loose.

4. The internal circuit is loose (due to long-distance transportation, bumps), you need to open the cover and

check the internal connection line.
