The Hefty® II CC/CV is a portable, solid state controlled, voltage sensing wire feeder that operates on arc voltage and can be used with most constant voltage (CV) and constant current (CC) DC-type power sources. The unique design of the Hefty® II CC/CV allows operation in a constant wire feed speed mode when used with CV power sources, and in a voltage sensing wire feed speed mode when used with CC power sources.

The Hefty® II CC/CV’s rugged steel-reinforced, flame-retardant polyethylene case totally encloses the solid state control circuitry, welding wire, and wire drive system. This portable and lightweight unit is designed with a hinged, latched door allowing quick and easy access to the contactor, welding wire and feedhead assembly. It has an insulated top carrying handle and the control panel is recessed to protect the controls.

Features of the Hefty® II CC/CV include quick change feed rolls allowing the operator to change feed rolls without the use of tools, a hand-operated plastic knob for clamping the welding gun into the feedhead and two gear driven feed rolls which will accommodate wire sizes up to and including 5/64” diameter

GOT POWER?™ Features

• Quick Change Feed Rolls - Feed rolls can be changed without the use of tools 
• Contactor - Allows welding wire to remain electrically “cold” until the gun switch trigger is depressed
• Gas Valve - Controls “on/off” flow of shielding gas
• Powerful, Permanent Magnet DC Drive Motor - Accommodates fast speed demands of small diameter wire and low speed, high torque demands of large diameter wire
• Polarity Insensitive - Weld with straight or reverse polarity 
• Electronic Controlled Protection Circuitry - Protects against voltage spikes, shorted or locked motor, shorted contactor coil and shorted gas valve coil 
• Electronic Brake - Solid state control offers precise stopping of the wire
• Feed Roll Pressure Release - Allows operator to change feed rolls or wire while retaining preset feed roll pressure
• Welding Gun Holder - Extends life of welding gun and contact tips

Compatibility The Hefty® II CC/CV is designed to operate on arc voltage and will work with most constant current (CC) or constant voltage (CV) DC-type power sources. When connected to a Hefty® II CC/CV, the maximum allowed open circuit voltage of the power source is 100 VDC.
