Victor Technologies™ has redesigned its Thermal Arc® 186 AC/DC inverter for HF GTAW, lift GTAW, and SMAW. It features 15 amps more GTAW power than the Thermal Arc 185, as well as a digital operator interface.
The inverter provides a welding output of 10 to 200 amps with a duty cycle of 20 percent for GTAW at 200 amps/18 V. SMAW duty cycle is 16 percent when welding at 120 amps/26.6 V and is suitable for welding with 6011, 6013, 7014, 7018, and other electrodes up to 0.156 in. dia.
The 48.4-lb. unit uses 208- to 230-V input power and provides advanced AC wave shaping and pulsed DC GTAW controls for controlling the weld puddle and weld bead profile, reducing heat input, and increasing travel speeds. AC frequency control is adjustable between 15 and 150 Hz. Pulse frequency for pulsed GTAW is adjustable between 0.5 and 200 pulses per second, and peak pulse width is adjustable between 15 and 80 percent.
