Picture of Single-Phase AC Type

Single-Phase AC Type

Quick overview

Generally considered the best for welding thick plates and copper stranded cable as the weld time can more widely adjust than electrostatic sorted energy type of welders.

Single-Phase AC Type

With low peak weld currents there is little less chance of weld spattering and burrs (hair like protrusions) that are often produced from dirt or other surface contaminants during the weld preheat or up slope cycle.


Product Features:

  • Excellent for integration with automatic operations because of small size and multiple welding functions: Pre-Heating, Up-Slope and Cooling Time
  • Weld heat actuation control for both Squeeze and Hold functions
  • Automatic switching between two (2) set-up conditions
  • Built-in power source voltage compensation
