The Powermax125 uses an inverter power supply (IGBT) for efficient conversion of input power. Smart Sense technology monitors and adjusts gas pressure automatically during operation, eliminating manual pressure changes. SpringStart technology ensures consistent arc starting without high-frequency interference. The system can be powered by engine-driven generators, requiring a minimum of 40 kW for full 125 ampere output.[2]
The Powermax125 is intended for cutting and gouging of electrically conductive metals such as mild steel, stainless steel, and aluminum. Specific cutting methods include drag cutting, fine feature cutting, flush cutting at a 45° angle, mechanized cutting on tables or automation, and gouging in either max-control or max-removal modes.[2]
Typical user industries include job shops, heavy equipment manufacturing, industrial pressure vessel fabrication, steel service centers, shipbuilding, and structural steel construction.[1]

The severance cut thickness (hand cutting) is 57 mm (2-1/4 inches) at a speed of 125 mm/min (5 ipm).[2]
The duty cycle is 100% at 125 A when operated with input voltages of 480/600 V (CSA) or 380/400 V (CE/CCC).[2]
Clean, dry, oil-free air or nitrogen is required. For cutting, the recommended flow rate is 260 l/min (550 scfh) at 5.9 bar (85 psi); for gouging, 212 l/min (450 scfh) at 4.1 bar (60 psi).[2]
Eleven Duramax Hyamp torch styles are available, including designs for hand cutting, portable automation, X-Y table cutting, extended reach cutting, and robotic cutting and gouging.[2]
Recommended cut thickness is 38 mm (1-1/2 inches) at 457 mm/min (18 ipm) and 44 mm (1-3/4 inches) at 250 mm/min (10 ipm).[2]
