How to choose a plasma cutter

When both speed and cut quality matter, plasma cutters are the answer. Plasma cutters enable clean, dross-free cuts with minimal heat input on both ferrous and non-ferrous materials. At Welders Supply, you'll get free shipping on all plasma cutters and all orders over $300.

Consider materials & thickness.

When choosing a plasma cutter, your first consideration is the thickness of the material you want to cut. Thick material requires higher amperage. If you plan on cutting both thick and thin materials, consider a high amperage machine with variable power. See the specifications tab of any plasma cutter on Welders Supply to see its cut capacity.

Consider cut speed.

Another important consideration: how fast do you want your plasma cutter to cut? Welders Supply carries a wide range of high-speed plasma cutters with capacities from as small as 1/8” up to 1”. The Hypertherm Powermax 30 XP, for instance, cuts through ½” mild steel three times faster than an oxyacetylene torch and has a lower operating cost.

Consider the consumables you'll have to use.

Plasma cutter consumables are pieces that wear down with use and must be replaced. Typical plasma cutters use a stack of various consumable parts that must be checked periodically for wear and replaced when worn down. The new Hypertherm Powermax SYNC line of plasma cutters makes this process much easier by combining all consumable parts into a single easy-to-swap cartridge, simplifying inventory management and reducing the time it takes to swap consumable parts. With the new SmartSYNC torches, you'll be able to have the right settings applied automatically and know exactly when to change your SmartSYNC consumable cartridges.

Consider the duty cycle you need.

The duty cycle of a plasma cutter is the percentage of time the machine can operate in a 10 minute time period. For example, a "50% @ 45 A" duty cycle means the plasma cutter can output 45 A of power for 5 minutes out of every 10 minutes the machine runs. Plasma cutters with higher duty cycle ratings are better for professional use in the field where speed of operation really counts.

Hypertherm Powermax Plasma Cutter with CPC Port

Consider whether you need CNC capabilities.

Plasma cutters with a CPC port or serial port are able to integrate with CNC machines for automated plasma cutting. Plasma cutters with a CPC or serial port can be used for any type of plasma cutting, including handheld, machine and robotic plasma cutting. Many Hypertherm plasma cutters have the option to come with a CPC port or be upgraded to use one, including the Powermax45® XP, Powermax65®/85/105/125, and Powermax65/85/105 SYNC™ models.
