MIG Welding Troubleshooting Tips

Mig Welding Troubleshooting Tips . The first thing to check is the gun’s nozzle. MIG-specific welding dikes (diagonal wire cutters) double as nozzle cleaners, but I usually clean the spatter off the end and inside of the barrel with regular wire cutters. Splatter can build up and arc out with the wire, and it can also break loose and fall into the weld puddle, contaminating it.

The Basics: MIG Troubleshooting. If using a weaving technique, momentarily hold the arc on the groove sidewall. If correcting the MIG gun angle does not remedy incomplete fusion, look to see if the welding puddle is too far ahead of the wire. If so, increase your travel speed and/or the welding current to correct the problem.

MIG Welding Troubleshooting. Problem 3: Burnback Cause: Using very slow wire feed speed or placing the gun too close to the base metal can lead to wire melting and Solution: Start by replacing the damaged contact tips and then increase the wire feed speed and make sure that you

MIG Welding Trouble Shooting: The Ultimate Guide Ever. Air or drafts from floor/overhead fans, open doors, and nearby machinery. Prevent the sources of air or similar drafts. Moisture from water, condensation due to welding (at/below 50 degrees F), morning dew. Evaporate the moisture by preheating the metal to 200 to 220 degrees F.
