Troubleshoot Common Welding Problems

Start with the symptom. Check the most likely setup, consumable, and machine causes before replacing parts.

Porosity in Welds Check shielding gas, leaks, contamination, wire condition, travel speed, and cup or nozzle setup. Troubleshoot porosity → Wire Feed Issues Check drive roll tension, liner wear, contact tip size, spool drag, gun angle, and wire condition. Fix wire feed issues → Arc Instability Check the contact tip, ground clamp, cable condition, liner seating, gas flow, and machine settings. Diagnose arc problems → Machine Overheating Check duty cycle, blocked vents, fan operation, extension cord size, ambient heat, and workload. Check overheating causes → Helmet Not Darkening Check batteries, sensitivity, delay, shade setting, blocked sensors, cover lens condition, and test mode. Fix helmet darkening issues → Fume Protection Check ventilation, respirator type, filter rating, cartridge condition, facial seal, and work material. Review fume protection →
