Fixing the minor failures by yourself

If your welding machine suddenly stops working, don’t panic. Often, the issue stems from minor human errors—such as incorrect connection or adjustments. Below are some typical troubleshooting steps you can take to resolve common problems:

1. Machine Fails to Start (Power Indicator is Off)

Check if the mains plug is properly connected and if there is voltage in the socket.
Inspect the connection of the network cable to the input relay unit. Remove the cover from the welder to check the mains terminals.
The machine may be in safe mode due to excessively high mains voltage.

2. Machine Turns On but Doesn’t Weld

Check the power supply network (ensure the input voltage or current meets the required levels).
Inspect the extension cord to ensure it matches the equipment’s parameters.
Listen for the power relay; you should hear a slight click when it’s turned on.
For PRO series welders, check the device settings—functions may be set to maximum. Reset to factory settings following the device manual.

3. Arc Disappears During Welding (Yellow LED is On)

Reset the welder to its factory settings, particularly if voltage reduction or short arc welding mode is activated.
Check the power supply network for low input voltage or current.
Verify that the extension cord meets the welder’s specifications.
Make sure the power relay is functioning.
The machine may be in overheat protection mode. Allow the fan to cool down the system before turning it off.

4. Electrode Sticks

Check the connection polarity.
Ensure the electrode is not humid.
Adjust the welding mode, as the current setting may be too weak for the selected electrode.

5. Wire is Not Feeding

Check if the wire spool has run out.
Test wire feed by pressing the button on the torch.
Press the wire feed button on the machine itself. If this works, you may need to repair the torch button.
Inspect the contact tip to ensure the wire hasn’t welded to it.
Ensure the wire feed channel is clear and the wire isn’t being crushed.
Check the feeder settings to confirm that the motor is not turned off.

6. Gas is Not Supplied

Ensure there is gas in the cylinder.
Test gas flow by pressing the button on the torch.
Use the “gas test” function on the machine. If it works, repair the torch button.
Verify the gas valve is not blocked and the gas hose is uninterrupted.

7. No Electric Current When Torch Button is Pressed

Check if the equipment is properly connected to the power supply.
Make sure the torch is connected to the welder.
Ensure the feeder unit’s mains plug is connected to the positive (“+”) terminal.

8. Poor Welding Quality (Wire Spitting)

Confirm the gas supply is adequate.
Check if the gas regulator pressure matches the required level.
Inspect the welding torch for any damage.
Ensure the rollers or channel match the diameter of the wire being used.
Verify the machine’s settings (voltage + wire feed speed).
Reset to factory settings and adjust the mode accordingly.

9. Excessive Molten Metal Splashing

Adjust the welding mode to a more suitable setting.
Change the torch angle for better control.
Ensure the gas supply hose is intact and free of leaks.
Check the polarity of the connection.

10. Shallow Weld Penetration

Adjust the welding mode to increase penetration.
Reduce the wire feed speed.
Ensure the edges of the parts being welded are clean.
Consider using a smaller diameter electrode or wire for better results.
