Protection against radiation and burns
▯
Warn of the danger to the eyes by hanging up a sign saying “Caution,
do not look into the flames!”.
▯
Work areas are to be shielded so as to protect people in the vicinity.
▯
Keep unauthorised persons away from the welding work.
▯
Do not set up fixed welding locations in the immediate vicinity of
light-coloured or glossy walls.
▯
Windows should be blocked off to at least head height to prevent the
escape or reflection of radiation, e.g. by painting with a suitable paint.
Risk of burns due to flying sparks
The spraying welding sparks can cause painful burns. Therefore, observe
the following guidelines:
▯
Always wear a leather apron.
▯
Use leather gloves.
▯
For overhead welding, wear suitable headgear.
▯
Ensure that your trouser cuffs fall over your shoes.
▯
Wear sturdy and insulated shoes.
Risk of accidents due to spattering slag
When it sets, the slag is hard and brittle. Afterwards, it can be chipped off
using the chipping hammer – sharp-edged particles may fly up that could
seriously injure your eyes.
Therefore protect your eyes by wearing suitable protective goggles when
removing slag.
Risk of fire due to flying sparks
If molten or incandescent metal and slag particles fall onto flammable sub-
stances, these can ignite and cause a fire. Therefore, remove all flammable
objects from the working area before commencing welding work. Keep a
suitable fire extinguisher at hand.
Pay particularly close attention to the following materials.
▯
Paper
▯
Rags
▯
Textiles
▯
Wood and wood fibres
▯
Rubber
▯
Plastic
▯
Petrol
▯
Oils
▯
Tar-like substances
▯
Paints and solvent
Risk of explosion
Both the welding function and the superheated weld joint itself can cause
explosions. Therefore, do not use the appliance in a potentially explosive
environment containing combustible liquids, gases or paint mist.
Please also note:
▯
When the flux-core welder is in operation, do not lay the torch on the
flux-core welder itself or any other electrical appliance.
▯
Before finishing the welding work, do not touch the flow nozzle or any
other metal object with which the flow nozzle is in contact.
▯
Disconnect the appliance from the power immediately after completing
your welding work.
▯
Ensure that no cable is wrapped around any body part.
▯
Make sure that you are not within the welding current circuit. The welding
torch and earth must always be on the same side.
EMC appliance classification
As per the standard IEC 60974-10, this appliance is a welding unit with
class A electromagnetic compatibility. Thus it complies with the correspond-
ing requirements for industrial and domestic use. In residential areas, it
may be connected to the low voltage electricity supply.
Even the flux-core welder complies with the emission limits of the standard,
arc welding appliances can nevertheless cause interference to sensitive
systems and appliances.
The user is responsible for any interference caused by the electric arc during
welding and must take appropriate preventive measures. The user must
pay close attention to the following:
▯
Power, control, signal and telecommunication lines
▯
Computers and microprocessor-controlled appliances
▯
TVs, radios and other playback appliances
▯
Electronic and electrical safety appliances
▯
People with pacemakers or hearing aids
▯
Measurement and calibration systems
▯
The electromagnetic immunity of other systems in the vicinity
▯
The time of the day at which the welding work is to be carried out.
To prevent possible interference radiation, we recommend:
▯
Fitting a mains filter to the mains connection or shielding it with a metal
pipe
▯
Maintaining the flux-core welder regularly and keeping it in good
condition
▯
Weld cables should be as short as possible, completely unwound and
running as close to parallel with the floor as possible
▯
An equipotential bonding should be provided
▯
The workpieces should be properly earthed
▯
Any appliances susceptible to interference radiation should moved out
of the welding area, if possible, or shielded.
