Plasma Cutter Buying Guide
Choosing the right plasma cutter means understanding output, consumables, and how you will use the machine — handheld, on a CNC table, or both:
Output Amperage and Cut Capacity
30-50A: Light Shop and DIY Use
Handles mild steel up to 1/2-inch at rated cut speed. Perfect for automotive, artistic metalwork, and trailer repairs. Can pierce 5/8-inch at reduced speed. The most common choice for home shop users.
60-80A: Production and Heavy Fabrication
Cleanly cuts 3/4-inch steel at speed. Suited for structural steel, heavy equipment repair, and small production shops. Requires 240V single-phase or 3-phase power at this output level.
85-100A+: Industrial and CNC Production
Cuts 1-inch and above. Designed for CNC tables running continuous production. Requires high-flow air supply and 3-phase or 240V single-phase service. These are tool-and-die and job-shop machines.
Pilot Arc vs. Contact Start
The arc start method affects how you can use the machine:
- Contact start (drag cut): Touch the tip to the metal to start the arc. Simple, lower cost, but tip wears faster and cannot pierce expanded metal or grating cleanly.
- High-frequency pilot arc: Starts arc without contact. Longer consumable life, cleaner starts on rusty or painted surfaces, required for grid material and CNC tables.
- Blowback pilot arc: Mechanically starts the arc without RF interference. Preferred for CNC use because HF start can interfere with CNC controllers.
CNC Table Tip
If you plan to use your plasma cutter on a CNC table, always choose a machine with a blowback pilot arc (not high-frequency) to avoid interfering with your CNC controller electronics.
Consumable Cost and Availability
Consumables — tips, electrodes, shields, and swirl rings — are your ongoing operating cost:
- Hypertherm: Most expensive consumables but longest life. Powermax tips last 3-5x longer than budget brands. Total cost per cut is often lower despite higher upfront cost per set.
- Miller/Lincoln: Mid-range consumable cost. Readily available at welding supply stores nationwide.
- Budget brands: Low per-set cost but shorter life. Frequent changes slow production and increase contamination risk.
Always use manufacturer-specified consumables. Off-brand tips on a Hypertherm torch dramatically reduce performance and consumable life.
Air Supply Requirements
Your compressor must keep up with your plasma cutter's air demand:
- 30-45A machines: 4-6 CFM at 70-90 PSI. A 20-gallon compressor works for short cuts; 60-gallon minimum for extended work.
- 60-80A machines: 6-8 CFM at 90-120 PSI. Requires a 60-gallon or larger compressor running continuously during cutting.
- Air quality: Moisture and oil in the air line destroy consumables rapidly. Always run a coalescing filter and auto-drain moisture separator on your plasma air line.
Calculate Your Electrical Load
Determine if your shop can handle your plasma cutter and compressor simultaneously.
CNC Table Compatibility
Running a plasma cutter on a CNC table requires specific machine features:
- Machine torch interface: A control connection for the CNC to fire the torch and read arc voltage. Budget machines lack this.
- Arc voltage output: Used for torch height control (THC) to maintain consistent standoff during cutting.
- Blowback pilot arc: Avoids RF interference with CNC electronics (see above).
- Recommended machines: Hypertherm Powermax series, Lincoln Tomahawk 1500, and Everlast machines with machine torch options are all proven CNC-table choices.
