Project Description

model-501-0The 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.

HIGH DEPOSITION RATE=HIGH PRODUCTIVITY

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
