Lincoln Electric Power Wave 300C Advanced AC/DC Multiprocess Welder, 200-600V
The Lincoln Electric Power Wave 300C Advanced AC/DC multiprocess welder delivers 300 A at a 100% duty cycle across SMAW, GTAW, GMAW, FCAW and CAG, and adds high-frequency and AC capability. Access to STT, Rapid X and Low Fume Pulse extends it to advanced processes, and PowerConnect accepts 200-600 V input for work from technical training to industrial fabrication.
STT, Rapid X and Low Fume Pulse give precise arc control, good out-of-position performance and low spatter on steel, stainless steel and aluminum. PowerConnect adjusts automatically to 200-600 V at 50 or 60 Hz, single- or three-phase, holding welding output constant across the whole input range, and the Tribrid Power Module provides high power factor and efficiency.
Ready-to-run features include an integrated cart with a tilting bottle rack, cable management hooks and a Twist-Mate TIG connection with gas solenoid, and the fan runs only when needed. Power Wave Manager and Checkpoint Production Monitoring access is standard, and the optional 115 V (10 A) AC duplex receptacle uses Surge Blocker Technology so grinders, which can draw 60 A or more at peak surge, do not disturb the weld.
