Welder error codes and what they mean

The display shows an error code or a fault light. Codes are different for each brand and model. Your manual has the exact list. These are the groups most codes fall into.

What to check first

1. Write down the code and your model number. A photo of the screen works too.
2. Look the code up in your manual. It names the problem and often the first thing to try.
3. Heat codes: let the machine cool with the fan running.
4. Input power codes: check the outlet, the cord and the breaker. Skip extension cords.
5. Feeder or motor codes: check the drive roll, liner and spool brake.
6. After you fix the cause, turn the machine off and on once to clear the code.

Safety: Do not keep welding with a fault showing. You can damage the machine.

What it usually is

• Too hot or too much load
• Power coming in too low or too high
• A feeder or motor problem
• A failed part inside the machine
