      If you're experiencing poor welding performance with your ESAB Welding System, start by checking that the welding current supply and return cables are correctly connected and that the correct current value is set. Also, verify that the correct welding wires are being used and inspect the main power supply fuses. Finally, check the wire feed unit, ensuring that proper rolls are applied and the pressure of the wire feeder's pressure rollers is correctly set.
