Welding Project: DIY Downdraft Plasma Table

Andy shows how to build a downdraft cutting table attachment tailored for the ArcStation™ 30FX. Utilizing the FILTAIR® 130, this attachment can effectively “eat the smoke” that’s created while plasma cutting. It’s portable and easy to disassemble and store, providing a hassle-free solution for a cleaner workspace.
