The Model 501 Hot Wire Power Supply is designed to increase the deposition rate of the filler wire in the weld joint by resistively preheating it.
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.
Features:
- 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.
The Model 501 Hot-Wire Power Supply can be used:
- as a stand-alone unit with its own Operator Pendant
- with the AMI Model 415 Power Supply/Controller
- or by and external weld process controller programmer
