DC multiprocess capability provides versatility and outstanding arc performance in CV (MIG) and CC (Stick, TIG, CAC-A). Fan-On-Demand™ which operates only when needed. This feature reduces noise, energy use and the amount of contaminants pulled through machine. Internal digital voltage control (DVC) enables operator to preset weld voltage in the CV mode before striking an arc. Lift-Arc™ allows TIG starting without the use of high-frequency. Starts the arc without contaminating the weld with tungsten. Inductance/Dig Control with pre-settable digital display to optimize MIG/Stick performance. Line voltage compensation keeps power constant even if power input varies by ±10%. Process selector switch automatically sets contactor requirements, eliminating confusion caused by several switch combinations and making this machine very “operator-friendly.” Excellent power efficiency for exceptional value and return on your investment. Enhanced environmental protection: all critical components housed in protective enclosures. 115 VAC duplex receptacle provides 15 amps of auxiliary power. Thermal overload protection helps prevent machine damage if the duty cycle is exceeded or airflow is restricted. Dimension™ NT 450 MIGRunner ™ Package shown Help codes help troubleshoot and service power source. Help codes are displayed on the volt/amp meters. Reduces the time needed to get the machine back into service. Power source is warranted for 3 years, parts and labor. Original main power rectified parts are warranted for 5 years.
