JINSLU CUT50L 50A Non-Touch Pilot Arc Air Plasma Cutter
JINSLU CUT50L 50A Non-Touch Pilot Arc Air Plasma Cutter
JINSLU CUT50L Non-Touch Pilot Arc Air Plasma Cutting Machine
Take your metalworking projects to the next level with the JINSLU CUT50L — a professional-grade, high-frequency inverter plasma cutter built for industrial and workshop use. Featuring a non-contact pilot arc, this machine strikes an arc without touching the workpiece, delivering cleaner cuts, minimal slag, and significantly extended consumable life. Whether you're cutting stainless steel, mild steel, copper, aluminum, or cast iron, the CUT50L handles it all with speed and precision.
Made in Mainland China.
Key Features
- Non-Touch Pilot Arc (220V): Cuts rough, painted, and rusty surfaces efficiently with minimal slag. No contact with the metal required — delivers superior cut quality and longer consumable life. Recommended breaker: 30A on 220V.
- Powerful Cutting Ability: 10–55A DC output. Achieves a ½" ideal clean cut and ¾" maximum severance cut on 220V. Compatible with stainless steel, alloy steel, mild steel, copper, cast iron, aluminum, and chrome using non-hazardous compressed air.
- Advanced Single-Tube IGBT Inverter: Converts 50/60Hz AC to DC, then to high-frequency, lower-voltage rectified output (inverter frequency: 25–50 kHz). Pulse Width Modulation (PWM) output delivers high-power DC supply with 30%+ improved conversion efficiency. Quiet operation and energy-saving performance.
- Wide Voltage Compensation: Built-in power supply voltage compensation device keeps the machine operating reliably even when voltage fluctuates within ±15% of rated voltage. When using extension cords, use a heavy-duty cord (10 or 12 AWG or greater) to minimize voltage drop.
- Easy Pilot Arc Start: High-frequency oscillation principle makes arc striking effortless. Features pre-gas supply and delayed gas shut-off functions for consistent, reliable starts every time.
- Fan-on-Demand Cooling: The intelligent cooling fan only activates when the machine needs it — reducing noise, lowering power consumption, and minimizing debris drawn into the unit.
- Widely Compatible Materials: Designed for stainless steel, alloy steel, mild steel, copper, and other non-ferrous metals — ideal for fabrication, automotive work, construction, and industrial applications.

Frequently Asked Questions
Q: Does the JINSLU CUT50L require the torch to touch the metal before cutting?
A: No. The CUT50L features a non-touch pilot arc system that uses high-frequency oscillation to initiate the arc without any contact with the workpiece. This means you can cut painted, rusty, or rough surfaces with better quality and without damaging the torch tip or nozzle.
Q: What metals can the CUT50L plasma cutter cut?
A: The JINSLU CUT50L is designed to cut a wide range of conductive metals, including stainless steel, mild steel, alloy steel, carbon steel, copper, cast iron, aluminum, and chrome. It uses standard compressed air (60–70 psi recommended) as the plasma gas — no hazardous gases required.
Q: What air compressor and breaker do I need for the CUT50L?
A: JINSLU recommends using a compressor that can deliver 60–70 psi of air pressure for optimal cutting performance. For electrical setup, a 30A breaker on a 220V circuit is recommended to ensure safe and stable operation.
Q: Why doesn't the cooling fan run as soon as I turn the machine on?
A: The CUT50L uses a fan-on-demand cooling system that only activates when the internal temperature requires it. This is completely normal and by design — it reduces noise, saves energy, and prevents unnecessary dust from being drawn into the machine during standby.
Q: What is the maximum cutting thickness of the CUT50L?
A: The maximum severance cut on 220V is ¾" (approximately 19 mm), with an ideal clean cut of ½". In millimetre terms, it handles carbon steel and stainless steel up to 16 mm, aluminum up to 6 mm, and copper up to 5 mm.
