OVERVIEW

Keep Your Thermal Arc 186 Running Cool

Is your Thermal Arc 186 AC/DC welder overheating or shutting down unexpectedly? It might be time to replace the cooling fan. The W7005520 Fan Assembly is the direct factory replacement for your machine, designed to get you back to welding quickly and safely. Over time, fans can become clogged with shop dust, bearings can fail, or motors can burn out, leading to reduced airflow and potential damage to your welder's expensive internal boards.

Don't risk your machine with a generic fan that might not fit or push enough air. This genuine part drops right into the existing mounts inside your 186 AC/DC unit. It plugs into the existing harness, making the swap straightforward for those comfortable with machine repair. By restoring proper airflow, you ensure that your welder can handle the amps you need, whether you are TIG welding aluminum or burning stick electrodes.

Why choose this OEM fan?

  • Perfect Fit: No drilling or splicing wires required.
  • Reliable Performance: Matches the original specs for speed and air volume.
  • Peace of Mind: Protects your welder from heat damage.
