400 A MIG welding head assembly

The Bernard 360-K40 Shortstub head assembly is built for MIG welding (GMAW) at up to 400 A. Its brass construction and over 2,000 pounds of gripping pressure let the electrode be bent for difficult weld access. The design allows the electrode to be used within one inch of the high heat. It is a direct replacement head for Shortstub stick electrode holders.

Thermal and power behaviour in normal use

The brass body conducts heat away from the contact zone during high-current MIG runs. High impact resistance protects the head from mechanical shock in the workshop. Quick electrode installation and head replacement reduce the time the assembly spends at peak temperature. No active cooling or power-draw figures are provided by the manufacturer.

Upgrade context and when the change makes sense

This head replaces a worn or damaged Shortstub head on an existing holder. The jump is worth it when gripping pressure has dropped or when the electrode can no longer be positioned close to the work. It is not for operators using a different holder series or a process other than MIG welding (GMAW). Buyers who need a complete holder rather than a replacement head should look elsewhere.

Questions about this item

How do I install the Bernard 360-K40 head onto my Shortstub holder and what step is often missed?

Slide the head onto the Shortstub holder until it locks; the step often missed is verifying the electrode sits within one inch of the high-heat zone for proper contact.

What maintenance or replacement will the 360-K40 head need over time?

Replace the brass head when electrode grip weakens or the high-impact body shows cracking; electrodes themselves are consumables swapped per job.

What limit appears first when running the 360-K40 at its 400 A rating for long periods?

Heat buildup in the brass head assembly becomes the limiting factor before the 2,000-pound grip pressure drops.
