Specifications to check

Below are some of the options to consider when choosing a cutter and we've also included a section on how plasma cutters work and their advantages. You'll also find lists of compressor models and stockists if you haven't already got one available to use with your cutter and need to buy one.

Required thickness of metal to be cut

This is a bit obvious but you need to check the maximum metal thickness that can be cut, allowing perhaps 30% extra capacity. Most plasma cutters will cope with at least 6 mm of mild steel, with semi-professional models going up to 15 mm. Thicknesses are usually quoted for mild steel, so be careful if you want to cut stainless or alloy as cutting capacity will be less.

Voltage and Phase

Most of these models work on 240V and single phase with the higher priced plasma cutters running on 400/440V three-phase supply. This will help if you need better economy, control and efficiency, as the three phase gives a smoother response and power delivery.

Compressor included or not

As plasma cutters use gas in some form or another, often compressed air, then a separate air supply and/or compressor is needed. Typically 5bar pressure is adequate for most of the models we've found, although you will need to check the required flow rate as well, which is shown using 'cfm', for example '5cfm'. However, some models have an integrated compressor.

Use of Inverters

Older analogue plasma cutters used to run large mains frequency transformers which were heavy. The use of transistor inverters is now commonplace and this increase is transforming efficiency, therefore reducing the weight. Typically weights are now less than 12kg making portability easier.

Plasma Cutter uses

Their key operating characteristics make plasma cutters suitable for applications that are impossible or difficult to fulfil in other ways. Firstly you can cut from one side of the sheet of metal with very little clearance on the other side and a low risk of damage to other materials, since the plasma arc only conduct on to the required metal to be cut.

Also the high speed cooler gas surrounding the cut removes heat and debris rapidly. This is a very useful characteristic for car body repairs, auto workshops and garages.

Plasma cutters also make it easy to cut curves and angles accurately, so their use in fabrication is widespread.

The whole cutting process for thicker metal plate is also obviously much easier than using any type of saw, and the cut finish is much better and neater.
