The best portable plasma cutters for DIY projects are compact inverter units that run on 120V or 240V and need only a shop compressor. Listed cut capacities mostly fall between 1/4 and 5/8 inch of steel. Choose by the power you actually have: a 120V outlet limits output, while a 240V circuit unlocks the full amp rating.
This roundup compares six popular Amazon options. We have not hands-on tested them. Specs come from manufacturer pages, retailer pages and the Amazon listings, and anything we could not confirm is marked per the listing so you can check it before you buy.

How to Choose a Portable Plasma Cutter
Check these points before you compare prices:
- Power: Match the machine to your outlet and breaker. Dual-voltage cutters usually deliver less output on 120V than on 240V, so read the manual for breaker size and amp range at each voltage. See our 110V vs 220V plasma cutter guide.
- Thickness: Compare the clean cut rating, not just the maximum. The maximum (severance) cut is slow and leaves a rough edge.
- Start method: Contact-start (PT31 style) torches touch the metal to start. Pilot-arc torches start without contact and cope better with rust, paint and expanded metal.
- Air supply: Plan on a compressor with a regulator and a moisture trap. Use the PSI and airflow figures in your model’s manual.
- Duty cycle: This is how long the machine cuts before it needs to cool. Check it at the voltage you will use.
- Consumables: PT31 and AG60 style parts are widely sold, which keeps replacement tips and electrodes easy to find.
bestarc CUT35A: Light Sheet Metal on 110V
The CUT35A is the entry-level pick here: a small IGBT inverter cutter for thin to medium sheet metal, brackets and light fabrication.
Listed specs
- Output: 35A on 110V single phase, per the listing. This is a 110V unit, not dual voltage.
- Capacity: 1/4 inch clean cut and 1/2 inch maximum cut, per the listing.
- Features: post-flow cooling and 2T/4T trigger modes, per the listing.
- Torch: PT31 style, contact start.
Pros and limits
- Good for sheet metal, brackets and hobby work from a standard outlet.
- 35A means thicker plate is slow, and the maximum cut leaves a rough edge.
- A contact-start torch is harder to use on rusty or painted steel than a pilot-arc machine.
- You still need an air compressor. Check the listing for whether a regulator is included.
Reboot 60A: Dual-Voltage Value Pick
The Reboot 60A (model RBC6000D per the listing) is a touch-arc cutter that runs on 120V or 240V with automatic voltage detection. Our Reboot 60A plasma cutter review covers it in more detail.
Listed specs
- Output: 10-35A on 120V and 30-60A on 240V.
- Listed capacity: up to 1/2 inch steel at 120V/35A and up to 5/8 inch at 240V/60A. Treat these as maximum cuts, not clean cuts.
- Weight: about 8.7 lb (8.69 lb per the listing).
- Torch: PT31, touch arc (not pilot arc).
- Air: the listing suggests 70-75 PSI from a compressor rated at 90 PSI and 60 L/min or higher.
Pros and limits
- Good if you want to start on 120V and add a 240V circuit later.
- Light enough to carry between the garage and a job site.
- Touch-arc start, so it is not ideal for mesh, heavy rust or paint.
- Needs an external compressor and a suitable circuit.
FLARING 65A: Highest Listed Output
FLARING sells this as a 65A cutter that runs on 120V or 240V. We could not find a manufacturer spec sheet, so every figure below is per the listing.
Listed specs
- Rating: 65A, dual voltage (120V/240V).
- Design: IGBT inverter with a PT31 torch and spare consumables, per the listing.
Check on the listing before you buy
- Clean cut and maximum cut thickness.
- Output at 120V versus 240V.
- Duty cycle at the voltage you will use.
- Whether it starts by touch or by pilot arc, and what compressor it needs.
Pros and limits
- The highest rating in this group on paper.
- A top-line amp rating usually applies at 240V only, so do not expect it from a 120V outlet.
PrimeWeld 50A: Standard 50A Option
PrimeWeld lists the CUT50 as a 50A, 110V/220V cutter with a 1/2 inch clean cut and a 60% duty cycle, per a retailer page. PrimeWeld’s own site also sells the newer CUT50DP, so confirm the exact model name on the Amazon listing before you order.
Listed specs
- CUT50: 50A, 110V/220V, 1/2 inch clean cut, 60% duty cycle, per the retailer page.
- CUT50DP (per PrimeWeld’s product page): 20-50A on 220V and 20-40A on 110V, 12 mm clean cut, 16 mm severance on 220V, high-frequency pilot arc, AG60 torch.
Pros and limits
- A common 50A size that suits sheet and plate up to about 1/2 inch.
- Only the CUT50DP is described as pilot arc. Check which one the listing shows.
- You still need a compressor and a 240V circuit for full output.
TOOLIOM CT520D: Plasma Cutter Plus TIG and Stick
The CT520D is a 3-in-1 machine that cuts with plasma and also welds TIG and stick. It suits a small garage that cannot fit three separate machines.
Listed specs
- Output: up to 50A plasma, 200A TIG and 200A stick, per the TOOLIOM listing.
- Input: 110V/220V dual voltage. Output is lower on 110V. The similar Lotos-branded CT520D spec sheet lists 35A plasma, 100A TIG and 80A stick on 110V, against 50A, 200A and 200A on 220V. Check TOOLIOM’s own figures.
- Capacity: the Lotos CT520D sheet lists a 1/2 inch maximum plasma cut.
- Gas: TIG welding needs shielding gas and a flow meter. Plasma cutting needs compressed air.
Pros and limits
- One machine covers cutting, TIG and stick.
- You need both an air supply and a gas supply.
- Combo machines weigh more than cut-only units. The similar PrimeWeld and Lotos versions list roughly 24-32 lb.
- TIG and stick output on 110V is limited, so a 240V circuit makes more sense.
Tosense CUT55: Compact 55A Option
The Tosense CUT55 is listed as a small 55A dual-voltage cutter. We could not find a manufacturer spec sheet, and the Amazon link in the table above opens search results, so confirm the exact product on the listing page.
Listed specs
- Rating: 55A, 110V/220V, per the listing.
- Features listed: IGBT inverter, digital amp display and a PT-31 torch with spare tips and an air filter.
Pros and limits
- Small and light enough to store on a shelf and carry to the job.
- Built for DIY workloads, not heavy daily shop use.
- Budget a separate regulator and moisture trap if the kit does not include good ones.
Safety and Setup Basics
Plasma cutting throws sparks and hot metal. Before the first cut:
- Wear eye protection with the correct shade, gloves, a long-sleeved cotton or flame-resistant shirt and closed boots. Our plasma cutter safety rules and PPE checklist has the full list.
- Clear flammables from the work area and keep a fire extinguisher nearby.
- Ventilate the space. Cutting galvanized, painted or coated metal releases fumes you should not breathe.
- Clamp the work clamp to bare, clean metal near the cut.
- Use dry, filtered air at the pressure in your manual, and test settings on scrap first.
Which Portable Plasma Cutter Should You Pick?
- Only a 120V outlet and thin metal: the bestarc CUT35A, or a dual-voltage unit run on 120V.
- 120V now, 240V later: the Reboot 60A.
- You want the highest listed amp rating: the FLARING 65A, after you confirm its specs.
- A 50A cutter with a known brand name: the PrimeWeld, after you confirm the model.
- Cutting plus TIG and stick in one machine: the TOOLIOM CT520D.
- Small size matters most: the Tosense CUT55, after you confirm the listing.
Match the amp rating to your thickest regular cut, then check that your circuit and compressor can support it. For more models, see our portable plasma cutter picks for garages.
FAQ
What is the best portable plasma cutter for DIY projects?
It depends on your power. For a 120V-only garage, a 110V unit such as the bestarc CUT35A is enough for thin sheet metal. If you can add a 240V circuit, a dual-voltage cutter such as the Reboot 60A gives more cutting thickness.
Can a portable plasma cutter run on a regular 120V outlet?
Yes, many can, but output is lower than on 240V. Dual-voltage models list a reduced amp range on 120V, so they cut thinner metal and more slowly there. Check the manual for the right breaker size.
Do I need an air compressor for a portable plasma cutter?
Yes, unless a model has a built-in compressor, which you should confirm on the listing. You need clean, dry air at the PSI and airflow in your manual, plus a regulator and moisture trap.
How thick can these plasma cutters cut?
Listed figures range from about 1/4 inch clean cut on the 35A bestarc to about 5/8 inch maximum on the Reboot at 240V. The clean cut is always thinner than the maximum, so size the machine for your regular cuts.
Is a plasma cutter, TIG and stick combo worth it?
It can be if space and budget are tight, because one machine covers three jobs. The trade-off is more weight and the need for both air and shielding gas, and a dedicated cutter may be simpler if you only cut.
