Tweco 1400-1041 Teflon Conduit Liner Aluminum Mig

Product Description

The TWECO 1400-1041 is a Teflon conduit liner engineered for MIG welding applications that use aluminum wire. Teflon construction provides significantly lower friction than standard steel liners, giving aluminum wire the smooth, consistent feedability it requires to prevent birdnesting and drive-roll slippage. The liner measures 10 feet in length and accommodates wire diameters from 0.040 to 3/64 inch. A brass alloy machined stop on the back end of the liner secures positioning inside the gun and makes installation straightforward. The manufacturer part number is roll-stamped on the outer surface of the brass stop for quick field identification. This liner is sold as a single unit and weighs 0.25 pounds.

This conduit liner is designed for use with Mini-MIG guns, including the 35TF series as well as PULSEMASTER and PullMaster MIG guns. Aluminum wire welding is common in fabrication, automotive, and marine applications where lightweight structural welds are required. The liner is a consumable replacement part that MIG welding technicians and fabricators swap out during scheduled maintenance or when feed resistance increases. Proper liner selection is critical when running aluminum wire because the soft wire deforms easily under excess friction, making a low-friction Teflon liner the standard choice for this wire type.

Key Features

• Teflon construction reduces friction for reliable aluminum wire feedability
• Accommodates wire diameters from 0.040 to 3/64 inch
• 10-foot liner length suits standard MIG gun cable assemblies
• Brass alloy machined stop on back end secures liner position and simplifies installation
• Part number roll-stamped on brass stop for fast identification in the field
• Compatible with Mini-MIG, 35TF series, PULSEMASTER, and PullMaster MIG guns

Compatibility

Designed for use with TWECO Mini-MIG guns, including the 35TF series, PULSEMASTER MIG guns, and PullMaster MIG guns. Intended for use with aluminum welding wire in the 0.040 to 3/64 inch diameter range.

Installation Notes

Installation and replacement of conduit liners should be performed by a qualified welding technician. Always power down the welding machine and disconnect the MIG gun from the wire feeder before removing or inserting a liner. Feed the liner through the gun cable from the back end, seat the brass stop firmly, and trim the front end to the correct length before threading the contact tip and nozzle. Do not use a steel conduit liner in place of this Teflon liner when feeding aluminum wire, as increased friction will cause feeding problems and wire burnback.
