Low Cost Plasma Cutter: What to Look For
Dual voltage, cut thickness, duty cycle and air supply: the numbers that decide a low cost plasma cutter, with 4 cutters scored.
On this page
A low cost plasma cutter is worth buying when it matches the metal you cut, the power you have and the air you can feed it. The cut thickness decides whether it handles the job, the duty cycle decides how long it cuts before resting, and the air supply decides whether the arc stays stable. This guide walks through the numbers that decide a cut, the air supply, and the cutters below, scored for home garage work.

Cons
- Air compressor is bought separately
- Recommended air pressure of 70 PSI needs a compressor that can feed 250 liters per minute
- No spare consumables are listed as included
- Maximum clean cut of 1/2 in is below the VEVOR 9/16 in clean cut at 220V
FLARING 240V Plasma Cutter With Built In Air
A 45A plasma cutter with a built-in air compressor, so no external compressor is needed, cutting clean to 3/8 in and 5/8 in at most.
Pros
- Built-in air pump, no external compressor needed
- Overload protection and automatic pressure adjustment
- Spare set of consumables included
- Cuts steel, stainless steel and aluminum
Cons
- No warranty term is stated
- 240V only, so no 110V option
- 45A is the lowest maximum output here
- No product dimensions are stated
60A Plasma Cutter,110V/220V Dual Voltage High
A 60A dual-voltage plasma cutter with a contact arc start and LED display, cutting to 19mm at most on carbon steel, stainless steel, aluminum and copper.
Pros
- 60A maximum output on dual voltage 110V and 220V
- Maximum cutting capacity of 19mm
- Cuts carbon steel, stainless steel, aluminum and copper
- Contact arc starts easily on rusty or painted metal
Cons
- No warranty term is stated
- No weight or dimensions are stated
- Contact arc, not a non-touch pilot arc
- No duty cycle is stated
Low cost plasma cutter: cut thickness, duty cycle and air supply
The cutters in this set run from 45A to 65A, with maximum cuts from 5/8 in to 3/4 in. The VEVOR cutter leads on thickness, at 3/4 in at 220V. The SILATU cutter follows at 2/3 in at 220V. The FLARING cutter cuts clean to 3/8 in and 5/8 in at most, and the haxiaoer cutter cuts to 19mm at most. Only the SILATU listing states a duty cycle, at 60%.
| Cutter | Max cut | Clean cut | Duty cycle |
|---|---|---|---|
| VEVOR 65A Plasma Cutter | 3/4 in at 220V | 9/16 in at 220V | Not stated |
| SILATU STC550P 55A | 2/3 in at 220V | 1/2 in at 110V | 60% |
| FLARING FC450 45A | 5/8 in | 3/8 in | Not stated |
| haxiaoer 60A Cutter | 19mm | Not stated | Not stated |
Cut thickness is the first number to match. A manual that calls for a clean edge wants the clean cut figure, while rough sizing can use the maximum cut figure.
Air supply: the part buyers forget
Three cutters here need an air supply, and one carries its own. The SILATU listing notes the air compressor is bought separately, and calls for 70 PSI with a flow rate of 250 liters per minute, through a 1/4 NPT connector. The FLARING cutter is the exception: its built-in air pump means no external compressor is needed.
Low cost plasma cutter for a home garage: the gear
The gear below runs from a 45A cutter with its own air pump to a 65A cutter with the thickest max cut in this set.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Check the power and air before the first cut
- Match the voltage. The SILATU, VEVOR and haxiaoer cutters take 110V and 220V; the FLARING cutter takes 240V only.
- Feed the air. The SILATU listing calls for 70 PSI and 250 liters per minute. The FLARING cutter carries its own air pump.
- Mind the duty cycle. Only the SILATU listing states one, at 60%, so the other listings give no figure to compare.
- Leave circuit work to an electrician. A cutter on a 220V or 240V circuit needs a licensed electrician for the wiring, not a DIY workaround.
- Use the post-time. The SILATU post-time adjusts from 3 to 15 seconds, and the VEVOR PT time from 1 to 6 seconds.
FAQ: garage tools
What thickness can a low cost plasma cutter cut?
Maximum cuts in this set run from 5/8 in to 3/4 in: the VEVOR cutter at 3/4 in at 220V, the SILATU cutter at 2/3 in at 220V, the FLARING cutter at 5/8 in, and the haxiaoer cutter at 19mm.
Do I need an air compressor for a plasma cutter?
It depends on the cutter. The SILATU listing notes its air compressor is bought separately, while the FLARING cutter has a built-in air pump and needs no external compressor. The haxiaoer listing states a 50 to 60 PSI working pressure, so it needs an air supply.
Can I run a plasma cutter on 110V?
Three cutters here take 110V and 220V: the SILATU, VEVOR and haxiaoer cutters. The FLARING cutter takes 240V only. On 110V the SILATU runs at 15 to 40A and the VEVOR clean-cuts to 1/2 in, so expect thinner cuts on 110V.
What is 2T and 4T on a plasma cutter?
They are trigger modes, listed on the SILATU and VEVOR cutters. In 2T mode the trigger needs continuous pressure, while in 4T mode you release the trigger after starting, which suits longer cuts.
What does duty cycle mean on a plasma cutter?
The duty cycle is the share of a work period the cutter can run before it needs to rest. Only the SILATU listing states one, at 60%. The other listings here state no duty cycle, so compare them on cut thickness and power instead.
