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

Restore Smooth Welding Performance

Is your MIG wire stuttering, slipping, or burning back to the tip? The culprit is often a dirty or worn-out gun liner. The ESAB Red Liner, 2.00M (Part Number 0700300503), is the perfect replacement solution for welders running 1.0mm to 1.2mm (0.040" - 0.045") wire. The liner acts as the backbone of your MIG torch, guiding the wire through the cable assembly. When a liner gets kinked or clogged with shop grime and wire shavings, the resulting friction ruins your arc control and leads to frustrating "bird-nesting" at the feeder. Swapping out your old liner is one of the cheapest and most effective ways to make your welder run like new again.

This specific liner comes in a 2.00-meter length, making it ideal for shorter torch assemblies or specific custom setups. It features a durable steel spiral design that resists crushing and kinking, ensuring a clear path for the wire. The bright red jacket isn't just for looks—it's a quick reference code that tells you exactly what size wire it handles. This prevents the common mistake of trying to run thick wire through a small liner (which causes jamming) or thin wire through a large liner (which causes the wire to wander and lose electrical contact).

Installation is straightforward. Simply remove the old liner from the back of your gun or Euro connector, unroll the new ESAB liner, and slide it in. If the liner is slightly longer than your torch neck requires, it can be easily trimmed to the perfect fit using side cutters. Whether you are welding mild steel in an automotive shop or performing fabrication work in a garage, relying on high-quality consumables like this ESAB liner ensures that your focus stays on the puddle, not on fighting the equipment. Don't let a bad liner ruin your welds; keep a spare ESAB Red Liner in your toolbox to minimize downtime.
