If the protection indicator light is on, it could be due to inner overheating. In this case, wait for the inner temperature to decrease for the machine to recover to normal. Alternatively, it might be due to a power supply issue with over or lack of pressure exceeding 15%. The machine should recover when the voltage returns to normal.
What to do if my HUGONG POWERTIG 300DPIII Welding System has no Argon output?
If there is no Argon output, there are several potential causes. First, check the flow meter and hose to ensure they are feeding air to the welder. If that's not the issue, the main control board or the electromagnetic gas valve might be broken, requiring replacement. Lastly, the air path could be blocked. In this case, clean any foreign bodies and dredge the air path.
