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).
5.3 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.
Close the acetylene and the oxygen tank valve by turning them rightward. Also close these
valves during extended breaks.
5.4 Replacing the gas cartridge
Î Close the gas cartridge valve by turning it rightward.
Î Pull the Maxi gas cartridge tank with its gas cartridge valve and the hose line upward and
out of the mounting.
Î Unscrew the Maxi gas cartridge leftward from the gas cartridge valve.
Î Make sure that the gasket in the gas cartridge valve is present and intact.
Î Only original Rothenberger Maxi gas cartridges may be used. Install a full Maxi gas
cartridge into the gas cartridge valve by turning it rightward.
Î Insert the full Maxi gas cartridge, with the gas cartridge valve and hose line installed,
into the mounting.
5.5 Replacing the oxygen and acetylene tank
Î Close the oxygen tank valve by turning it rightward.
Î Screw off the oxygen pressure regulator by turning it counter-clockwise with the enclosed
key.
Î Remove the oxygen tank from the mounting. Replace the empty oxygen tank with a full
one.
Î Screw the oxygen pressure regulator clockwise onto the oxygen tank.
Î Make sure that the gasket in the oxygen pressure regulator is present and intact.
Î In so doing, make sure that the connections are free of oil and grease.
5.6 Malfunctions and maintenance
Problem Cause / Solution
The flame turns yellow Either the oxygen tank valve is closed or the oxygen tank
is empty.
Open the oxygen tank valve.
Replace the empty oxygen tank with a full one.
The flame gets smaller or
lifts off the burner. Either the acetylene valve is closed, or isn’t open wide
enough, or the gas cartridge is empty.
Open the acetylene valve by turning it (farther) left, or
replace the acetylene tank.
Regularly check the hoses for cuts and leaks (visual inspection).
Replace the hose package with its single-tank fuse if the single-tank fuse has triggered after
a flashback.
Hoses become porous with time. Therefore, replace the hose package as soon as small cuts
appear on the hoses (optional).
