Buying Guide
Buying a 100 Amp Plasma Cutter: A Quick Guide
Choosing a 100 amp plasma cutter unlocks the ability to slice through thicker metals. But with numerous options available, focusing on key factors is crucial for a wise purchase.
Cut Capacity and Metal Thickness
Confirm the cutters rated cut capacity, expressed in inches. A 100-amp machine should cleanly sever 1-inch mild steel, and often handle thicker materials with a severance cut. Consider the metals you frequently work with, such as stainless steel or aluminum, to ensure the cutter meets your needs.
Duty Cycle
The duty cycle indicates how long the machine can operate at its maximum amperage before needing a cool-down period. Look for a high duty cycle, like 60% at 100 amps, meaning it can run for 6 minutes out of every 10. Higher duty cycles minimize downtime, especially when performing extensive cutting tasks.
Power Requirements and Portability
100 amp cutters demand significant power, typically requiring a 240V input. Check your available power supply. Consider portability if you need to move the machine around a workshop or to different job sites. Weight, handle design, and machine size are key factors here.
