Verdict

  • 90% of no-arc issues are air, ground, or worn consumables — easy checks first.
  • Keep air dry and at the right flow; moisture kills arc stability and tips.
  • Ground clamp on clean metal, close to the cut; inspect cable for heat damage.
  • Confirm torch safety interlocks and cup seating; replace cheap tips more often.

FAQ

Some are fine for light jobs, but safety certification/materials vary.

Different sellers, specs, and quality control; Amazon includes better warranty.

Look for vague specs, inconsistent reviews, poor fasteners, missing safety markings.

Local suppliers mean faster replacements and verified compatibility.
