ABSTRACT:
A hot air torch for the welding of plastic featuring an air flow around and about the inner portions of tubular members which entrains unwanted internally generated heat prior to the welding tip to provide a torch body which is safe to the touch while at the same time providing suitably heated air at the welding tip. Excess accumulated heat is vented overboard in the vicinity of the welding tip.
