The Model 501 is suitable for welding high-quality stainless steel tanks and vessels that are rotated during welding. The addition of hot wire can optimize the corrosion resistance and/or mechanical properties of the weldment and have a beneficial effect on the material performance in service. The hot wire GTAW process produces a very clean weld with a very low incidence of porosity and increases filler deposition rates similar to GMAW.
Constant Voltage (CV) True RMS mode-of-operation
Calibrated Precision Closed Loop Servo Output Control
Voltage Feedback Sensing at the wire feed tip or internal to the Power Supply
True RMS instrumentation Outputs (Amps and Volts)
Optional Manual Remote Programming Pendant
Control input for connection to an external controller
The Model 501 implements advanced technology with significant competitive advantages. To minimize magnetic interference , the unit uses AC current to preheat the wire. This current is far more precise than competitive machines, being very close to a true sine wave.
