CobraMAX

Push-Pull Gun

When you’re ready to move up to a push-pull wire feeding system, consider the CobraMAX. This easy-to-handle air-cooled gun shares many of the same features with our top-of-the-line Python push-pull gun, including an ergonomic handle design, fingertip controls, and foolproof set up. With a fixed gooseneck design and 150 amp 100% duty cycle rating, the CobraMAX is an ideal push-pull gun.

Advantage Lincoln

• Superior push-pull wire feeding technology for smooth feeding and minimized damage to the wire.

• Lightweight, ergonomic handle - weight distribution is equally balanced front and back for better feel and control.

• Sturdy bottom-mounted trigger can be operated with either hand.

• Fine adjustment of wire feed speed is easily accomplished using the multi-turn adjustment dial.

• Flip-up drive roll cover for easy access to wire. Quick wire release for easy wire adjustments.

• Complete with a knurled drive roll and a grooved idler roll, which will handle both steel and aluminum wire from .030-1/16" (0.8-1.6mm) diameter.

• Interchangeable contact tips, drive and idler rolls, and conduits between Prince guns – no need to stock multiple consumables.
