• Wind Tunnel Technology - internal air flow that protects electrical components and PC boards from dirt, dust, debris greatly improving reliability
• Fan-On-Demand power source cooling system operates only when needed, reducing noise, energy use and the amount of airborne contaminants pulled through the machine
• Lift-Arc start provides tig arc starting without the use of high frequency
• Adaptive Hot Start for stick - automatically increases output amperage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion
• Lightweight, aerospace-grade aluminum case - offers protection with the benefit of reduced weight
• Inverter arc control technology - provides greater puddle control for superior 6010 Stick electrode performance
• LVC line voltage compensation - keeps welding output constant even if input power varies by +/-10%, line voltage compensation further expands to +37% and -59% when operating on 460 VAC
• Process selector switch - reduces the number of control setup combinations without reducing any features
• Large, dual digital meters - are easy to view and presettable to ease setting weld output
• Voltage range in CV mode: 10 - 38 volt
• Amperage range in CC mode: 15 - 600 amp
