Metal Thickness Plasma Cutter Amperage Chart

The chart below includes recommendations for stainless steel cutting amperage and material thickness when using a hypertherm xpr300 plasma system.

Metal thickness plasma cutter amperage chart.

The cut charts are divided into two areas. Although plasma can cut through painted metal it does require a solid connection on a clean part of the workpiece as close as practical to the work. Like a welding power source a plasma cutter s amperage and voltage capacities determine its size. It is important to try and work through all of the relevant suggestions provided as often there are many different factors to consider.

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. This is fine for most cutting jobs. 1 above water cutting pages 4 11 through 4 33 and 2 under water cutting where the water table water is 3 above the top. In addition to selecting the best gas combination selecting an appropriate cutting amperage is equally important to producing excellent plasma cutting results.

This plasma cutting tips reference guide offers several solutions to help improve cut quality.

The thickness of metal you will routinely cut and maximum metal thickness are important in selecting the right plasma cutter.

Most cutters for home use produce between 40 and 50 amps. For cut 50 amps works out well etc. Versa cut 40 plasma cutter air pressure amperage settings metal thickness 1 64 1 32 3 64 1 16 5 64 3 32 7 64 1 8 9 64 5 32 11 64 3 16 amps 20 20 20 20 20 20 20 20 20 20 20 20 psi 30 30 30 30 30 30 30 30 30 30 30 30. There are several factors to consider when purchasing a plasma cutter.

There are a lot of factors that go into producing a quality plasma cut. Cut charts the following cut charts provide the necessary information in order for the operator using the max200 machine torch system to be successful in plasma arc cutting. Check the ground connection to the work piece. For 3 8 cut 40 amps works out well for most brands of plasma cutters.

Units that double as welders often produce up to 200 amps and are more expensive.
