A normal plasma cutter is only half a machine — it needs a compressor beside it, an air line, a dryer and a power point for both. A plasma cutter with built-in air compressor carries its own air supply inside the cabinet. The FINELINE 100IC makes 4–5.5 kgf/cm² of air internally and feeds it straight to the torch, so it cuts anywhere there is a three-phase socket: site work, maintenance rounds, scrap yards, the back of a service van.
It is also two machines in one. The Cut/MMA selector turns the 100 A inverter into a stick welder for 1.6–4.0 mm electrodes, so the same unit cuts the plate and welds it. And when the job needs the last 5 mm, an external compressor takes cutting capacity from 30 mm to 35 mm.
For most site teams this plasma cutter with built-in air compressor replaces three things — a plasma unit, a compressor and a small stick welder — with one machine on castors.
Run on the built-in compressor, or flip to external when shop air is connected for 35 mm cuts and long production runs.
2T for short cuts; 4T for long cuts without holding the trigger.
Purge and confirm air flow before the arc fires.
Switch between plasma cutting and stick welding in one move.
Set 20–100 A on the dial, read it on the display; overcurrent alert protects the inverter.
On this plasma cutter with built-in air compressor the compressor module sits inside the cabinet behind the side vent and delivers 4–5.5 kgf/cm² of air to the torch. Because the air never leaves the machine there is no hose to kink, no water trap to forget and nothing extra to carry. Post-flow (5–20 s, adjustable) cools the torch after each cut.

Need more current for a fixed cutting bay? See the FINELINE 120 (120 A, CNC ready) or the standard FINELINE CUT-100 for use with shop air. The CUT 70 covers lighter sheet work. Plasma cutting basics are explained on Wikipedia.
Electrode holder for MMA, consumables (electrodes, nozzles, shields) and a CNC torch are quoted separately; the exact scope is confirmed on the quotation. See the full range on our products page.
