Plasma Cutter Drag Tip vs Standoff Guide
Real, shed-tested plasma cutter reviews, comparisons, and fix guides. I put popular machines and torches through cut tests, air-pressure setups, and consumable burn-rate checks so you know what actually works. You’ll find pilot-arc vs non-pilot-arc explainers, compressor sizing, standoff vs drag-tip results, and common “won’t arc” fixes. See today’s Amazon price on each review and, if you’re in NZ, grab PT-31, SG-55, and P-80 consumables direct.

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.
Key Specs / Setup
| Recommended Air | 5–6 CFM @ 90 PSI (dry, filtered) |
|---|---|
| Tip Gap | 1–2 mm with standoff guide for cleaner kerf |
| Leads | Keep short & undamaged; check ground clamp jaws |
| Common Torches | PT-31, SG-55, P-80 |
FAQ
Most hobby plasma cutters need 4–6 CFM @ 90 PSI; keep air dry to protect consumables.
Pilot arc starts without touching, handles paint/rust, and saves tips; non-pilot arc is cheaper but wears faster.
Check air pressure, moisture, tip/electrode wear, ground clamp, and torch safety switch.
Drag tips work but overheat; a 1–2 mm standoff keeps kerf clean and extends consumable life.
Match consumables to the torch model; mixing parts reduces cut quality and lifespan.
