Heavy duty portable plasma cutting machine

The Portable CNC Plasma Cutter is engineered for professionals who need high-precision, high-efficiency metal cutting in a compact and mobile design. Equipped with advanced CNC technology, high-stability linear guides, and a wide choice of plasma power supplies, this portable cutting system provides the same performance as a large gantry plasma cutter—at a fraction of the cost and footprint.

It is the ideal solution for metal fabrication workshops, construction sites, automotive repair, HVAC manufacturing, agricultural machinery, and on-site installation projects.

1. Choosing the Right Plasma Power Supply for Your Portable CNC Plasma Cutter

A plasma cutter’s cutting quality depends largely on the power supply, which generates the plasma arc used to cut metal. Selecting the correct power level ensures smooth edges, faster cutting speed, and longer consumable lifespan.

1.1 Recommended Plasma Power Supply Brands

Our portable CNC plasma cutter is compatible with both international and domestic plasma sources:

• Hypertherm Powermax 45/65/85/105
• Thermal Dynamics Cutmaster Series
• Huayuan LGK 40–200A
• Panasonic Plasma Source
• Other industrial-grade 40A–200A plasma systems

These power supplies offer stable arc ignition, superior cutting speed, and high reliability for industrial use.

1.2 How to Choose Plasma Power Based on Material Thickness

Tip: For metal over 30–40 mm, you can combine plasma cutting with optional oxy-fuel flame cutting.

5. Common Plasma Cutting Problems & Solutions

Problem 1: Excessive Dross Formation

Cause: Cutting speed too slow or plasma power too low

Solution: Increase cutting speed or upgrade to higher amperage

Problem 2: Arc Fails to Pierce Material

Cause: Plate too thick / torch height too high

Solution: Lower torch height, check pierce settings

Problem 3: Uneven or Slanted Edge

Cause: No THC or incorrect height control

Solution: Enable automatic THC for consistent quality

Problem 4: Consumables Burning Too Fast

Cause: Air pressure too low / poor air quality

Solution: Use clean, dry, oil-free compressed air
