Get a Grip: Revive Your PKB Torch

There is nothing more frustrating than trying to lay down a perfect bead with a MIG gun that feels like it's falling apart in your hand. If your ESAB PKB 250 or PKB 400 torch is held together by electrical tape, or if the handle is cracked and pinching your glove, it is time for an upgrade. The ESAB Gun Housing PKB 250/400 Compl is the direct replacement you need to get your favorite torch feeling brand new again. A solid, comfortable grip is the foundation of good torch control, and this replacement housing restores the original balance and feel you expect from ESAB equipment.

Welding guns take a beating. They get dropped, dragged, and exposed to intense heat day in and day out. When the plastic housing cracks, it’s not just an annoyance—it changes how the gun sits in your hand and can even make the trigger feel sloppy. This replacement kit includes the complete shell (both sides) and the screws to lock it all down tight. It is molded from durable, high-impact plastic that resists heat and takes a beating, so you can stop worrying about your tools and focus on the puddle. The texture is designed to provide a non-slip grip, even when you are wearing heavy leather welding gloves, giving you the confidence to maneuver the torch in tight positions.

Installation is straightforward and takes just a few minutes on the bench. You simply disassemble the old, broken halves, check your internal connections (it's a great time to blow out any dust or liner shavings), and screw the new housing in place. Everything lines up perfectly because it’s a genuine ESAB part—no modifying or forcing required. Once installed, you will notice the difference immediately. The trigger will sit correctly, the neck will be supported firmly, and the gun will feel solid again.

Don't let a broken handle compromise your safety or your weld quality. A cracked housing can expose you to internal electrical components or let shielding gas leak if the internal lines get pinched. Swapping out the housing is one of the cheapest and most effective repairs you can do to extend the life of your rig. Whether you are running a PKB 250 in a garage or a PKB 400 on a production line, this housing kit is the refresh your gear deserves. Keep your arc smooth and your grip steady with genuine ESAB parts.
