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.
