There is nothing more frustrating than a sputtering arc caused by a clogged or kinked liner. If you are running a Tweco Spray Master MIG gun and noticing drag in the wire feed or erratic arc starts, it might be time to swap out the liner. The Tweco 1640-1370 Conduit Tube is the direct replacement liner you need to get back to buttery-smooth welding. Designed to handle the rigors of daily shop use, this liner reduces friction inside the cable, allowing the drive rolls to push wire effortlessly to the contact tip.
A fresh liner is one of the cheapest insurance policies for good weld quality. Old liners often trap shop dirt and wire shavings, which can cause the wire to slip at the drive rolls or surge at the tip. This replacement conduit tube (MS64SFLX360ELF) is built to resist kinking and wear, ensuring that your wire feeds consistently even when the gun cable is looped or bent during out-of-position welding. It is designed specifically for the Spray Master series, meaning you won't have to fight with fitment issues—it slides right in and secures properly at the back end.
Don't let a bad liner ruin your beads or cause burn-back. Keeping a spare Tweco 1640-1370 in your toolbox ensures you can fix feeding problems immediately and keep the sparks flying. Whether you are in fabrication, repair, or manufacturing, this liner helps you maintain the control and precision your job demands.
