What to do if my ESAB Welding System has no power or arc?
- R
  Rita PalmerAug 5, 2025
  If your ESAB Welding System isn't powering on or producing an arc, verify that the input power supply switch is on. Also, check the display for any temperature fault indications, and ensure the system breaker hasn't tripped. Confirm that the input power, welding, and return cables are correctly connected, and the correct current value is set. Finally, inspect the input power supply fuses.

Why does my ESAB Welding System have wire feeding problems?
- J
  Joseph WilliamsAug 9, 2025
  If you're experiencing wire feeding issues with your ESAB Welding System, several factors could be at play. Ensure the wire spool brake is correctly adjusted and that the feed roller is the correct size and isn't worn. Also, verify that the correct pressure is set on the feed rollers and that the proper direction of motion is set based on the wire type. Check that the correct contact tip is used and that it's not worn. Finally, make sure the liner is the right size and type for the wire and that it isn't bent, causing friction.

How to troubleshoot porosity in ESAB EMP 320ic Welding System weld metal?
- A
  Ashley SmithAug 13, 2025
  To address porosity issues in the weld metal of your ESAB Welding System, consider the following: * Check that the gas bottle is not empty. * Ensure the gas regulator is not closed. * Inspect the gas inlet hose for leaks or blockages. * Verify the correct gas is connected and the correct gas flow is used. Additionally, maintain minimal distance between the MIG torch nozzle and the workpiece, avoid drafts that could disperse shielding gas, and ensure the workpiece is clean and free of oil or grease before welding.

How do I solve basic MMA (SMAW) welding problems with my ESAB EMP 320ic?
- J
  Julia PerkinsAug 22, 2025
  To solve basic MMA welding problems with your ESAB Welding System, ensure you are using the correct polarity. The electrode holder is usually connected to the positive polarity and the work lead to the negative polarity. If in doubt, consult the electrode data sheet.

- A
  andreaolsonAug 30, 2025
  To fix porosity in your ESAB Welding System's weld metal, start by checking that the gas bottle isn't empty and the gas regulator isn't closed. Inspect the gas inlet hose for leaks or blockages. Ensure the correct gas is connected and the correct gas flow is used. Keep the distance between the MIG torch nozzle and the workpiece to a minimum. Avoid working in areas with drafts. Also, make sure the workpiece is clean, free from oil or grease, before welding.
