Gas Lens vs Standard Collet Body
Choosing between a gas lens and a standard collet body affects shielding gas coverage, tungsten access, and how the torch behaves around joints, corners, and root passes. The right choice depends on…

MIG Weld Spatter Too High
If MIG weld spatter is running high, start with the basics: voltage, wire feed speed, shielding gas, stickout, and gun angle. Spatter is usually a setup issue, a consumable issue, or both.…

MIG Porosity Causes and Fixes
MIG porosity is gas trapped in the weld metal as it solidifies. It usually shows up as pinholes, worm tracks, or a rough weld surface. The main causes are shielding gas problems,…

Why Weld Beads Look Inconsistent
Inconsistent weld beads usually come from variation in heat input, travel speed, arc length, wire feed, shielding gas coverage, or joint preparation. The visible bead pattern is often the result of one…

Why Flux-Cored Wire Is Producing Worm Tracks (And How to Stop It)
Worm tracks in flux-cored welding are narrow, winding surface marks that usually show up on or beside the weld bead after the slag is removed. They are not normal bead texture. In…

TIG Torch Gas Leak Troubleshooting: Argon Loss, Black Tungsten, Porosity, and Torch Seal Checks
If a TIG torch has a gas leak, the weld may show black tungsten, gray weld color, porosity, sugaring on stainless, unstable starts, or a loud uneven gas hiss even when the…

Lincoln Power MIG Poor Arc Stability Troubleshooting: Wire Feed, Contact Tip, Liner, Gas, Ground, and Settings
Lincoln Power MIG poor arc stability usually comes from inconsistent wire delivery, poor electrical return, wrong setup, or shielding gas problems before it comes from a failed control board. Common symptoms include…

ESAB MIG Gas Flow Troubleshooting: Porosity, Nozzle Blockage, Gas Leaks, Flowmeter Settings, and Torch Checks
ESAB MIG gas flow problems usually show up as porosity, pinholes, black soot, popping starts, oxidized welds, or welds that look contaminated even when the wire feed feels normal. On ESAB Rebel,…

MIG Diffuser Clogging Symptoms: Porosity, Burnback, Spatter Buildup, and Poor Gas Coverage
A clogged MIG diffuser usually shows up as porosity, unstable arc starts, extra spatter, fast nozzle buildup, contact tip overheating, and repeated burnback. The diffuser sits behind the nozzle and routes shielding…

MIG Weld Spatter Reduction Troubleshooting: Settings, Gas, Stickout, Wire, and Gun Checks
Excessive MIG spatter usually comes from an unstable arc, not from one single bad part. Start with the high-impact checks: voltage and wire-feed-speed balance, shielding gas coverage, wire stickout, base-metal cleanliness, contact…
