0700300503 - ESAB Red Steel Liner 1.0-1.2mm x 2m

Precision Wire Feeding with ESAB Red Liner

The ESAB Red Liner (0700300503) is a critical component designed to maintain the efficiency and reliability of your MIG/MAG welding operations. Engineered specifically for welding wires ranging from 1.0mm to 1.2mm (0.040" to 0.045"), this liner ensures that the filler metal is delivered smoothly from the wire feeder to the contact tip. In industrial welding environments, the integrity of the wire conduit is paramount; even minor kinks or debris accumulation can lead to erratic feeding, arc instability, and costly downtime. This genuine ESAB part is manufactured to exacting standards, providing a low-friction path that minimizes drag and protects the wire from deformation.

At a length of 2.00 meters, this liner is tailored for specific torch configurations, potentially including shorter manual guns, push-pull intermediate connections, or specialized robotic arm setups where standard 3m or 4m liners would require excessive trimming. The liner features a robust steel spiral construction, which offers the necessary rigidity to prevent collapsing while maintaining enough flexibility to navigate the curvature of the torch cable. The red color coding is an industry-standard visual indicator, allowing operators and maintenance personnel to quickly verify that the correct liner is installed for the wire diameter in use, thereby preventing feeding issues caused by mismatched components.

Regular maintenance of the wire feeding system is essential for high-quality weld deposits. Over time, liners can become clogged with copper dust, dirt, and metal shavings, which increases friction and causes the wire to slip at the drive rolls. Replacing your old liner with this fresh ESAB Red Liner restores the system to optimal performance. It is compatible with a range of ESAB PSF torches and other Euro-connector style guns that utilize this specific length and diameter specification. By investing in genuine OEM parts, you ensure compatibility and longevity for your welding equipment.
