Description
Output Input
MIG Flux-Cored Submerged Arc Gouging
CV-655
Energy efficiency, reliability and exceptional performance are what set the CV-655
apart from the rest. Designed primarily for heavy-duty applications, the CV-655 is
an outstanding choice for MIG and flux-cored welding on mild steel, stainless steel,
aluminum and alloys.This sturdy, powerful DC power source handles CV semiautomatic submerged arc welding and arc gouging with ease. Equipped with electronic
and thermostatic protection, PC boards with built-in diagnostics and solid state
contactors, the CV-655 is built to last.
