KP4746-1 - Lincoln Electric KP4746-1 Short Back Cap for 17, 18, 26 Series TIG Torches

Get Into the Tightest Spots with the KP4746-1 Short Cap

Every TIG welder knows the struggle: you're trying to weld a collector on a custom header, or maybe a root pass inside a small diameter pipe, and the back of your torch keeps hitting the wall. You can't get the right angle, and your tungsten stick-out is getting ridiculous just to compensate. That is exactly why you need the Lincoln Electric KP4746-1 Short Back Cap in your kit. This little "button" style cap replaces the long tail on your 17, 18, or 26 series torch, instantly shrinking your torch's footprint and giving you the clearance you need to maneuver.

Switching to a short back cap changes the game for positional welding. By removing the long tail, you can fit your hand and torch into spaces that were previously impossible to reach. It requires you to cut your tungsten down to a shorter length (usually under 2 inches), but the trade-off in maneuverability is worth every second of prep time. This cap is built tough, using heat-resistant materials that won't melt or crack when you're pushing high amps on an AC aluminum job or running hot passes on stainless.

The KP4746-1 comes ready to rock with a fresh O-ring, ensuring you don't lose any argon out the back door. A leaky back cap is a silent killer of weld quality, sucking in air and turning your beautiful bead gray. With this genuine Lincoln part, you get a solid seal every time you tighten it down. It fits all standard 17 (air-cooled), 18 (water-cooled), and 26 (heavy-duty air-cooled) torches, so it's likely compatible with the rig you're running right now.

Don't get caught on a job site without one of these in your ditty bag. Whether you are building roll cages, fixing farm equipment, or welding sanitary stainless pipe, the Short Back Cap is the difference between a headache and a paycheck. It locks your tungsten in tight, seals up your gas, and gets out of your way so you can focus on laying dimes.
