In this video I am comparing the different types of Oxy/Fuel welding hoses. Have you noticed one has a “T” on the package and the other a “R”. The reason for this is the different characteristics of Acetylene and LP gas (Propane and Mapp). A rubber hose is used with acetylene because it won’t leak through or permeate rubber. Lp gas, however, will permeate rubber. This is why we use the grade “T” hose. This is a neoprene hose , which has an oil resistant lining on the inside so the gases will not leak through or permeate the hoses. Please match the proper hose with your fuel gas.

Welding Lenses and Cover Plates November 7th, 2009
Welding Cover Plates and Lenses. In this video I will do a comparison of the Polycarbonate lenses vs. The CR-39 lenses. I will demonstrate that the Polycarbonate which is impact resistant is the only lens I would use. |
