ESAB OPC Basic Sub-Arc Flux Recovery System

Save Flux and Time on Your Sub-Arc Setup

If you are running a sub-arc tractor, you know that managing flux can be a messy and expensive part of the job. The ESAB OPC Basic Flux Recovery Unit is the solution to stop wasting good flux and start keeping your weld zone clean. Designed to bolt right onto your ESAB A2 or A6 tractor, this system acts like a dedicated vacuum cleaner that works while you weld.

How It Helps You

Instead of stopping to sweep up piles of unused flux or letting it go to waste on the floor, the OPC Basic sucks it up right behind the torch. It uses a simple compressed air line—no extra power cords or heavy motors needed. The system separates the good, reusable granules from the dust and slag, dropping the good stuff right back into your hopper so it's ready to be used again instantly.

Built for the Shop

We know equipment takes a beating. That’s why the OPC Basic is built tough with no moving parts to break. It’s lightweight, so it won’t throw off the balance of your travel carriage or boom. The filter bag is easy to empty, and the suction nozzle is designed to pick up flux efficiently without disturbing the cooling weld bead.

Why You Need It

• Stop Shoveling: Automates the cleanup process so you can watch the arc, not the floor.
• Save Money: Reusing flux means buying less of it. The unit pays for itself in material savings.
• Better Welds: By filtering out the dust, you ensure only clean, consistent flux covers your arc.
• Easy Install: Hooks up quickly to your existing air supply and mounts securely to your rig.

Whether you are welding pipe, beams, or tanks, the ESAB OPC Basic makes the job cleaner, cheaper, and easier.
