tubing kits ?

Interesting in the factory video the welder at 3:05 was bench welding with a fan blowing directly on to the welding bench. I've never been able to make that one work. The few factory parts I've bought from BH for my scratch build have been very nice quality.

Fan was probably sucking air away rather than blowing on the work. Mark
