Six models for copper, aluminum, brass, both stranded and solid.
  • Stranded (sleeveless welding)-size range: .232” to 1.750” (27mm2 to 1970mm2).
  • Stranded (sleeveless welding)-size range: .232” to 1.750” (27mm2 to 1970mm2).
Solid-diameter range: .187” to 1.750” (4.76mm to 38.10mm).

Featuring extra heavy duty transformers, the AD Series butt welders are engineered for cost-efficient welding of aluminum, copper and brass, for continuous processing of wire, rod and cable products.
  • Welding of solid and also stranded conductors without sleeves
  • Unique two-stage upset (low to high pressure) mechanism
  • Convenient controls for precise selection of heat and spacing
  • Foot controlled dual clamping pedals for easy placement and adjustment
  • Pneumatically controlled heavy duty clamping mechanism for positive positioning
  • SCR electronic weld heat control for precise heat settings available
  • Welding die sets with special “Stellite” inserts for alignment and clamping prevent slippage
