Plasma Cutter + Accessories Selection — Quick Reference
Plasma cutting uses ELECTRICALLY-CONDUCTIVE IONISED GAS to cut electrically-conductive metals — STEEL + STAINLESS + ALUMINIUM — at speeds + thicknesses oxy-fuel cutting can't match. For fab shops + auto panel + maintenance.
| Plasma Cutting Item | Best For |
|---|---|
| Plasma Cutter (Inverter) | Workshop standard cutting — see plasma cutter guide |
| Plasma Torch (Hand-Held) | Manual cutting — workshop work |
| Plasma Torch (Machine-Mount) | CNC plasma cutter table |
| Consumable Electrodes + Tips | Wear consumables — replace per use |
| Swirl Rings + Retaining Caps | Torch consumable assembly |
| Standoff Guides | Maintain torch-to-work distance |
| Circle Cutting Attachment | Circular hole + curve cutting |
| Plasma Cut Chart (Speed / Amperage) | Per material thickness |
| Earth Clamp + Cable | Workpiece return path |
| Filtered Compressed Air | Plasma cutting requires CLEAN dry air |
Critical: CLEAN DRY AIR mandatory — water + oil in air supply destroys consumables + poor cut. Use air dryer + filter on compressor output. Replace consumables PROACTIVELY — worn tips = ragged cut + electrode damage. PPE — face shield + leather gauntlets + welding jacket. Brands: Bossweld, Tecmen. Companion: welding, welding safety, plasma cutter guide.
Plasma Cutting and Accessories
Plasma cutting uses an electrically-conductive ionised gas to cut electrically-conductive metals — steel, stainless, aluminium — at speeds and on thicknesses that oxy-fuel cutting can't match. For fabrication shops, automotive panel work, and maintenance teams, a plasma cutter is the right tool when oxy-fuel is too slow, mechanical cutting is too rough, and the metal in question is anything but mild steel. AIMS Industrial supplies plasma cutters, torches, consumables, and accessories for trade and industrial customers.
What's in the plasma range
- Plasma cutters (power sources) — inverter-based units in workshop sizes, with cutting capacity rated by amperage and clean-cut thickness
- Plasma torches — hand torches and machine torches for manual and automated cutting
- Consumables — electrodes, nozzles (tips), shields, swirl rings, and retaining caps — the parts that wear in service
- Accessories — cutting guides, circle cutters, gouging tips, and protective gear
- Compressed air filtration — plasma cutters need clean, dry air; an oil-and-water filter is essential
Sizing a plasma cutter
Plasma cutter capacity is rated by amperage and the matching clean-cut and severance thickness. As a starting point: 30A handles up to 8mm clean cut; 40-50A handles 10-12mm; 60-80A handles 16-20mm; 100A+ handles 25mm and beyond. Severance cut (the maximum thickness it'll cut through, even if not cleanly) is typically 1.5-2x the clean cut thickness. Match amperage to the heaviest material you'll routinely cut.
Compressed air supply — the often-overlooked spec
Plasma cutters need clean, dry compressed air at the cutter's specified pressure and flow rate. Workshop compressors that handle air tools without thinking can run out of capacity when feeding a plasma cutter — the cutter draws continuous high-volume air during the cut, not the intermittent air a tool uses. Check your compressor spec against the plasma cutter's requirement; a coalescing filter and dryer in the air line is essential for consumable life.
Consumables — what wears and how often
Plasma consumables are the wear parts that take the heat and arc damage. Typical change schedule: nozzles wear faster than electrodes (replace nozzles when the cut quality drops, electrodes when arc start becomes unreliable). Shields protect the front of the torch — replace when damaged. Keep a rotation kit on hand: running out of consumables mid-shift kills production.
Brands stocked at AIMS
Bossweld is the core brand for plasma consumables in our range — Australian-supplied and matched to the plasma cutter brands and models commonly running in this market. For specific cutter brands and torch types, we cross-reference consumables to OEM specifications.
Cutting practice
Maintain consistent torch-to-work distance (1.5-3mm typical), travel speed (matching the amperage and material), and cutting angle (90° to the work for square cuts, with adjustment for bevels). Drag-style nozzles let the torch tip rest on the work; standoff nozzles maintain a gap. Match technique to nozzle type. For straight cuts, a guide rail or cutting jig produces results that hand-held cuts can't match.

People Also Ask — Plasma Cutting & Accessories
Q: How is plasma cutter capacity rated, and what thickness can a 60-80A unit clean-cut?
Capacity is rated by amperage matched to clean-cut thickness — as a guide, 30A handles up to 8mm, 40-50A handles 10-12mm, 60-80A handles 16-20mm, and 100A+ handles 25mm and beyond.
Q: What does 'severance cut' mean on a plasma cutter's spec sheet?
Severance cut is the maximum thickness the machine can cut through at all, even without a clean edge — typically 1.5 to 2 times the machine's rated clean-cut thickness.
Q: What contamination in a compressed air line damages plasma cutting consumables?
Water or oil in the air supply damages consumables and produces a poor-quality cut, so a coalescing filter and dryer in the air line is essential for consumable life.
Q: Why might a workshop's existing air supply run short when feeding a plasma unit?
A plasma cutter draws continuous high-volume air during the cut rather than the intermittent air an air tool uses, so the supply's continuous flow capacity needs to be checked against the unit's requirement, not just its tank size.
Q: What's the difference between drag-style and standoff plasma cutting nozzles?
Drag-style nozzles let the torch tip rest directly on the work, while standoff nozzles maintain a set gap — the cutting technique needs to match whichever nozzle type is fitted.
