0700200181 - ESAB MXH Aluminum MIG Liner 0.9-1.6mm

Optimized Wire Feeding for Aluminum Applications

The ESAB Liner MXH Alum (SKU: 0700200181) is a critical replacement component designed specifically for the ESAB MXH series of push-pull MIG torches. Engineered to handle the unique challenges of feeding soft aluminum wire, this liner accommodates a diameter range of 0.9mm to 1.6mm (approximately 0.035" to 1/16"). In industrial welding environments, the integrity of the wire feed path is paramount to maintaining arc stability and weld quality.

Standard steel liners are often unsuitable for aluminum because their internal texture can shave the soft wire, leading to clogged liners and contact tips. This ESAB liner utilizes low-friction materials (typically Teflon or Polyamide based) to provide a smooth, snag-free path. This is particularly important in push-pull systems where the synchronization between the cabinet motor and the gun motor relies on consistent drag resistance. By minimizing friction, this liner helps prevent the common issue of bird-nesting at the drive rolls.

Proper maintenance of your MIG gun includes regular inspection and replacement of the liner. If you are experiencing erratic feeding, burn-back, or arc instability while welding aluminum with an MXH torch, a worn or contaminated liner is a likely culprit. Installing this genuine ESAB part restores the original performance specifications of your equipment, ensuring reliable operation for critical fabrication tasks.
