Frequent TIG Welding Issues

🔥 TIG Troubleshooting Guide

📋 Problem: Grey Stainless Steel Welds

• Bad gas coverage?
• Material overheating?
• CFH high enough?

🔧 Fix: Up your cup size (the bigger the better + use gas lens), slow travel speed + not enough filler = material overheating/gray welds. Up your travel speed and use enough filler to keep weld puddle cool. 20-25 CFH minimum, however the bigger the cup, the more CFH needed.

📋 Problem: Porosity

• Is CFH high enough (20-25 minimum)?
• Check for leaks in lines or torch.
• Is material clean (free of oil, paint, rust)?
• Is environment too windy?

🔧 Fix: Adjust gas flow, check connections, clean material, make sure air flow around the weld is not blowing away your gas.

📋 Problem: Arc Not Starting or Difficulty Starting Arc

• Is your machine connections correct?
• Is machine set to TIG high-frequency start if using foot pedal?
• Is machine set to TIG lift-arc if using torch to initiate arc?
• Is ground on clean metal and your welding clean metal?

🔧 Fix: Make sure your connections are setup for electrode negative (ground in positive terminal and electrode in negative), double check machine settings, double check material is clean where working and grounded.
