Bernard Model 4 Shortstub Replacement Head Kit

Don't Let a Worn Stinger Slow You Down

There is nothing more frustrating than trying to strike an arc with a loose stick rod. When your electrode holder loses its grip, you lose control of the puddle, and your hand starts to burn up from the excess resistance heat. The BERK40 Replacement Head Assembly is the fix you need for your trusted Bernard Shortstub Model 4. Instead of tossing out a perfectly good handle and cable connection, simply swap out the business end of the tool and get back to welding with a grip that feels brand new.

The Bernard Shortstub is legendary for a reason—it allows you to burn rods down to the numbers, saving you money on consumables. However, the head takes the brunt of the abuse. Spatter, arcing, and constant tightening eventually wear down the threads and contact points. This replacement kit (BERK40) gives you a fresh, solid brass head that locks your electrodes in tight. A tight connection means better current flow, a cooler running handle, and a smoother arc. It’s built to handle the full 400 amps that your Model 4 is rated for, so you can keep running large diameter rods without worry.

Installation is quick and easy, meant to be done right at the bench or in the field. By repairing your holder with this assembly, you ensure that your stinger holds the rod at the angle you set, without drooping or twisting while you're in position. Keep your gear in top shape and stop fighting your equipment. This replacement head restores the snap and reliability that made you choose a Bernard Shortstub in the first place.
