1.1 Intended use
The combination torch ROFLASH may only be used for the gas welding method. Depending on
the torch attachment, they can be used for welding, heating, brazing or gas cutting.
Performance:
ROFLASH
Welding: 0,2 - 14 mm workpiece thickness
Heating and brazing: size 1 - 8 or size 10 (according to gas type)
Cutting:
to 100 mm workpiece thickness
For a variety of applications, a complete range various welding, cutting or heating nozzles are
available with marginally differing performance capabilities and for use with the usual types of
fuel gas. For details, refer: section 2 technical data.
The information mentioned above includes reference values. They are valid for
unalloyed steel to 0.3% C when oxygen with a purity of at least 99.5% is used.
For the use of torches with several fuel gases, all the following identification letters are used
(refer: section 4).
Procedure available fuel gases (labelling)
Welding
acetylene (A)
Torch cutting acetylene (A), propane (P), natural gas (M)
Heating methyl acetylene (MAPP®), propadiene (Y)
Brazing hydrogen (H),
At all times the torch attachment shall only be used with the corresponding type of fuel gas
for which it is labelled. The optional use of different fuel gases with the same torch insert is
permissible only when the mixing of the fuel gas with oxygen or air is carried out in the
torch nozzle (gas-mixing nozzle). Accordingly, the gas type labelling of the torch nozzle
must be taken into account (refer section 4).
Combination torches may only be used for each application and procedure for which the
torch attachment is designed.
1.2 General safety instructions
ATTENTION! All instructions must be read. Errors due to non-compliance with the
instructions below can cause fire and/or severe injury. It is absolutely mandatory to
comply with the legal safety regulations and technical guidelines. Damages due to
operator error void the warranty.
KEEP THESE INSTRUCTIONS AVAILABLE.
1) Work
area
a) Keep your work area neat and clean. Messy or poorly lit work areas can lead to
accidents.
b) Do not work with the device in explosive environments containing flammable
liquids, gases or dusts. Tools create sparks that can ignite the dust, fumes or gases.
Make sure ventilation is adequate. If possible, do not work in closed spaces.
c) Keep children and other people away from the tool during use. If you are
distracted, you can lose control of the device.
d) Do not misuse the hoses for carrying or hanging the device. Keep the hoses
away from heat, oil, sharp edges and moving parts of the device. Damaged or
tangled hoses increase the risk of explosion.
e) Keep the device free of oil and grease. In pure oxygen, oils and greases of any kind
can explode on their own. Do not place the device near heat sources (heaters, ovens,
open flames, etc.).
