You may not need an enclosed chamber. Try our Open-Top Chamber (patent pending).

The Open-Top Chamber generates an argon cloud. It takes only a few minutes for the cloud to rise above the welding bed. (Imagine the dry ice cloud over a punch bowl.) The red curtain barrier keeps the heavier-than-air argon cloud in check.

Place your parts to be welded through the cloud onto the welding bed. Typically fifteen CFH is enough flow to maintain the cloud. Immediately before your torch's pre-flow begains, boost the argon flow to the chamber to thirty CFH. Start welding. After you weld, hold the torch in place during post-flow. Then reduce the chamber's flow back to fifteen CFH to save gas. It will stay ready for the next parts to be welded.

Our introductory model OT-1212 has a welding bed of 12 inches by 12 inches. Other sizes will be available in the future. Keep checking our website.
