0152470881 - ESAB PKB 400 Air-Cooled Push-Pull MIG Gun

Reliable Aluminum Feeding with ESAB PKB 400

The ESAB PKB 400 Push-Pull Gun (SKU: 0152470881) is a specialized welding tool designed to tackle the specific challenges of feeding soft welding wires, particularly aluminum. In industrial fabrication, feeding aluminum wire through standard MIG guns often leads to friction, buckling, and the dreaded "bird-nesting" at the drive rolls. The PKB 400 eliminates these issues by utilizing a synchronized motor located in the gun handle that pulls the wire while the main feeder pushes it. This dual-action system maintains constant tension, allowing for smooth, consistent wire delivery over longer cable lengths.

Rated for 400 Amps, this air-cooled gun is built for heavy-duty cycle applications where water cooling is not feasible or desired. It is an ideal solution for shipyards, trailer manufacturing, and automotive industries where welders need to move around large workpieces without moving the wire feeder. The gun connects seamlessly with compatible ESAB wire feed units, ensuring precise synchronization between the push and pull motors.

Durability is a hallmark of the PKB series. The robust housing protects the internal drive mechanism from impact and debris, while the ergonomic design ensures that the added weight of the pull motor does not compromise operator comfort. Whether you are welding thin gauge aluminum or heavy plate, the PKB 400 provides the stability and control required for X-ray quality welds.
