What to do if my ESAB ES 300i has no arc?
- HHayley LeonardAug 7, 2025
If your ESAB Welding System isn't producing an arc, verify that the display is on to confirm the power source is active. Also, ensure the setting panel displays correct values and the electrical power supply switch is turned on. Check that the mains, welding, and return cables are correctly connected and inspect the electrical power supply fuses.
