First open the adjusting valve for oxygen (16) on the hand grip (15) by turning to the left then
open the preheating oxygen valve (21) and the adjusting valve for fuel gas (17) by turning to
the left.
Ignite the flowing out gas mixture immediately using a suitable igniter. Adjust the flame into a
neutral condition by making adjustments on the preheating oxygen valve (21) or the adjust-
ing valve for oxygen (16) and the adjusting valve for fuel gas (17) (like the welding flame,
see 4.1).
Open the cutting oxygen wing lever (22) completely by tipping it to the left, or reregulate the
oxygen pressure (see Technical Data). Adjust the flame into a neutral condition again and
then close the cutting oxygen wing lever (22) by tipping it to the right.

Setting and extinguishing the flame

4.1

Setting the flame

With the hand dial marked red on the handle, adjust the size and appearance of the flame. If the
flame cannot be ignited or cuts off, the gas pressure is too high. In that case, choke off the gas
at the torch handle (the dial marked red) by turning it rightward.
The oxygen valve (the dial marked blue) must be completely open at the torch handle. If the
flame looks yellow, there is too much gas. Carefully choke the gas valve (the dial marked red) at
the torch handle by turning it farther rightward.
Then set to a neutral flame. This means that the strongly glowing blue-green core of the flame
must be sharply delineated from the blue border of the flame (the secondary flame).
4.2

Extinguishing the flame

To extinguish the flame, first close the gas valve (the dial marked red) and then the oxygen
valve (the dial marked blue) at the torch handle by turning rightward.
