This plasma cutting tips reference guide offers several solutions to help improve cut quality.
For cutting metals that are 1 4 inch thick or less a low cost low amperage cutter can be used as low as 25 amps will work.
There are a lot of factors that go into producing a quality plasma cut.
The chart below includes recommendations for stainless steel cutting amperage and material thickness when using a hypertherm xpr300 plasma system.
Units that double as welders often produce up to 200 amps and are more expensive.
This is fine for most cutting jobs.
Keep in mind this isn t the maximum thickness of cut that a plasma cutter is capable of cutting but rather it is a good rule to follow for decent cutting speed and quality.
The thickness of metal you will routinely cut and maximum metal thickness are important in selecting the right plasma cutter.
