Acetylene brazing equipment
AIRAC®
Acetylene brazing Torch
High-performance injection burner for “only” acetylene, for brazing/warming up of copper and Steel pipes up to 60 mm dia.. Due to the special construction of the burner, oxygen from the surrounding air is fed to the burner at atmospheric pressure with acetylene, producing a flame temperature of 2350° C with a concentrated, pointed flame for precise and fast working. Scale build-up at the heated surface is prevented by the nitrogen introduced into the air flow (shielding gas effect).

●

Turbine and combustion chamber effect, self-induced air: Maximum performance

●

Shut-off valve: Prevents uncontrolled escape of gas

●

High-performance injection burner only for acetylene, 2350° C: Powerful working
