Welding gas physical and chemical property:

1. Its diameter is 75mm, height 267 mm and gross weight 980g, convenient for holding and carrying.

2. The welding temperature can be reached 1350 degrees and the burning temperature can be reached 1980 Welding gas is a mixture of various hydrocarbons, principally, methylacetylene , propadiene and Propane(MAPP). It produces a relatively hot flame (2,976 degrees) with a high heat release in the primary flame (inner cone) (15,445kJ/m 3 ), less than for acetylene (18,890kJm 3 ) but much higher than for propane (10,433kJm 3 ). The secondary flame (outer cone) also gives off a high heat release, similar to propane and natural gas. The combination of a lower flame temperature, more distributed heat source and larger gas flows compared with acetylene results in a substantially slower pierce time.
