W7004925 - Thermal Arc Fabricator 181i Inlet Guide .023-.045

Keep Your Fabricator 181i Feeding Smoothly

If you own a Thermal Arc Fabricator 181i, you know it's a workhorse, but even the best machines need maintenance. The W7004925 Inlet Guide is the small but mighty part that sits right before your drive rolls. Its job is to funnel the wire from your spool directly into the feeder mechanism without snagging or scraping. Over time, the constant friction of steel or flux-cored wire can cut grooves into your old guide, leading to friction, drag, and those frustrating "birdnesting" issues.

This replacement guide is designed to handle the full range of wires you likely run, from thin .023" sheet metal wire up to heavy .045" flux-cored wire. Because it is a genuine part, it drops right into place without any modification. Replacing your inlet guide is one of the cheapest and easiest ways to troubleshoot feeding problems. If your wire feels like it's dragging or the motor is pulsing, check your guide—if it's worn, this W7004925 is exactly what you need to get back to welding buttery beads.

Don't let a five-dollar wear part ruin a day's worth of welding. Keep a spare inlet guide in your kit. Whether you are running solid MIG wire with gas or self-shielded flux core, this guide ensures the wire stays centered and moves freely, protecting your drive rolls and liner from unnecessary wear.
