85W09 - ESAB 85W09 Replacement Spring for ST-21 and HW-8 Torches

Keep Your ST-21 Torch Running Smoothly

There is nothing more frustrating than having a reliable piece of gear go down because of a small, inexpensive part. If you are running an ESAB (or classic Linde/L-Tec) ST-21 or HW-8 torch, you know these tools are built to last, but moving parts eventually wear out. The ESAB 85W09 Spring is the genuine replacement you need to restore the mechanical action of your torch and get back to laying beads.

Springs in welding torches often get overlooked until they snap or lose their bounce. Whether this spring is part of your trigger mechanism or helps seat your liner, a worn-out spring can make a premium torch feel sloppy and unreliable. A trigger that doesn't return crisply or a liner that shifts can cause wire feeding issues and hand fatigue, ultimately affecting weld quality. By swapping out the old spring with a fresh 85W09, you bring that factory-new feel back to your equipment.

Don't settle for generic hardware store springs that might not handle the heat or fit quite right. This is an authentic ESAB part, meaning it is made of the right metal to withstand the harsh environment of a welding shop. It’s a small investment to keep your trusty ST-21 operating at peak performance. We recommend keeping a spare in your toolbox so you are never caught off guard in the middle of a critical job.

Why Choose Genuine ESAB Parts?

• Perfect Fit: No need to bend or modify the spring to make it work; it drops right in.
• Durability: Built to handle the heat and abuse of daily welding.
• Peace of Mind: Protect your torch investment by using the parts the engineers designed for it.
