How to Choose
When selecting a small plasma cutter, the most important factors are cutting capacity, power input, portability, and consumable costs. Cutting capacity determines the maximum metal thickness you can cut cleanly, so match this to your typical projects. Dual voltage machines (110V/220V) offer flexibility between home and job site power sources. Portability is key if you need to move the tool frequently; models with built-in compressors provide more convenience but may add weight. Lastly, consider consumable availability and cost, as plasma cutters require regular replacement of electrodes and nozzles.
