Proper welding techniques and weld preparation are outside the scope of this manual. Welding the thicker metals noted below will require special techniques,
such as edge chamfering, that are outside the scope of this manual. Welding books and classes are recommended to teach proper methods and technique.
CLOSE
oxygen and acetylene torch valves, then fully close both cylinder valves
OPEN
both torch valves counterclockwise to allow all pressure to bleed out
TURN
pressure adjusting screws counterclockwise and remove them from regulators
HOLD
torch handle in one hand and striker in the other
OPEN
acetylene torch valve 1/4 turn and quickly ignite nozzle gas with striker
OPEN
slowly the acetylene torch valve farther until flame feathers at its edge slightly
ADJUST
flame to “Neutral Flame” by adding oxygen slowly
