Purpose-built liner for Magnum guns
This steel liner fits Lincoln Electric Magnum 100L, Magnum Pro 100L and Magnum Pro 175L MIG guns. It supports wire diameters from .035 in to .045 in for GMAW processes. The 15 ft length suits standard gun assemblies in automotive and fabrication shops.
Cable liner construction protects wire feed
The .06 in bore guides the electrode smoothly through the gun cable. Black and grey steel construction resists wear during extended welding runs. This replaceable liner maintains consistent feed performance without requiring gun disassembly beyond the liner itself.
15 ft length matches specific gun models
Verify your gun model against the compatible series list before ordering. The liner fits Magnum 100L, Magnum Pro 100L and Magnum Pro 175L guns using KP45-40-15 specification. Guns outside these series or requiring different bore diameters will not accept this liner.

Questions about this item
When should I replace the KP45-40-15 liner on my Magnum 100L gun?
Replace the liner when wire feeding becomes erratic or the 0.06 in bore shows visible wear, typically after several spools depending on wire type and feed speed.
What wire diameter range works reliably with this 15 ft liner during long MIG runs?
The liner accepts 0.035 in to 0.045 in wire; staying within this range prevents binding and ensures smooth feeding over the full 15 ft length.
Does the steel liner heat up or add resistance during all-day MIG welding?
The steel liner conducts heat from the gun but remains passive; it adds no electrical resistance and does not generate noise or extra heat on its own.
