Before You
Blame the Welder.
A MIG torch troubleshooting guide.
Follow the symptom. Inspect the small parts. Record what you actually find.
A small part can
interrupt a big job.
Wire feeding poorly? Wire fused to the tip? Shielding inconsistent?
The torch is a sensible place to start an external inspection. But one symptom can have several causes. Work from observations, avoid changing everything at once, and follow the procedure for your own gun.
01 / Inspection work order
Start with the symptom.
For gas-shielded MIG / MAG. These checks organize observations; they do not certify a repair or weld quality.
The inspection table
Look beneath the nozzle.
AI-generated conceptual states. Not a model-specific assembly or removal procedure.
No answer recorded.
Wire-feed trouble: inspect the contact tip, cable route and wire-feed setup.
Burnback: inspect the tip, feeding path and start/stop settings.
Shielding concern: inspect the nozzle, diffuser and gas supply.
