Plasma Cutter Inverter Model with CB50 4M Torch & 4M Earth Cable

Using a plasma cutter is a skill that requires time and effort to do well. Practice striking and maintaining an arc on scrap work pieces before beginning work. This will help you gauge the best settings for the plasma cutter for the material at hand.

1. You can cut metal that will conduct electricity up to approximately 1/2” thick mild steel or equivalent. Very thin or very thick metals are more difficult to cut cleanly.
2. Generally set the air pressure between 60 and 80 psi. Increased air pressure will increase plasma speed and cutting pressure. Air pressure and amperage should be adjusted in tandem.
3. Generally start with a mid-range amperage setting (32-33 amps) and adjust up or down from there. Increased amperage will increase cutting heat. This is needed with heavier and harder metals. However, increased amperage will reduce Duty Cycle time.
4. Move the cutting head more slowly for thicker and harder metals, and more quickly for thin or soft metals. Keep the cutting head moving while cutting.
