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 semiauto-
matic 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.
