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.
