CAUTION ! De UV light from the welding bow can damage your eyes or burn
your skin.
▪
Bow welding produces sparks en drops of melted metal. The welded surface remains hot
for quite a while.
▪
Vapors may occur that can be harmful to your health. Electrical shock can be lethal.
▪
Don’t come any closer than a radius of 15m from the light bow without protection.
▪
Protect yourself and the people around you from the harmful affects of the light bow.
▪
Caution: depending on the main circuit, it may occur that other users may experience
disturbances. In case of doubt please contact your power company.
6.1
Precautions.
▪
Leave adaptations to the main circuit, sockets, cables etc to qualified personnel, in
particular extension cables.
▪
When accident occurs: cut welder immediately from mains.
▪
If electrical contact voltages occur, shut the welder down and contact qualified person to
check welder.
▪
Welding current: always make sure electrical contacts are impeccable.
▪
Always ware insulating gloves on both hands for protection against: electrical shock, UV
radiation, melted metal, sparks etc.
▪
Ware solid, insulating (also in moist environment) shoes. Falling drops of melted metal
can result in severe burnings.
▪
Ware appropriate clothing: no synthetic fibers!
▪
Never look into the welding bow without protection! (Only with appropriate safety goggles)
UV radiation can cause severe damage to your eyes and skin (blinding, burning) that only
appear after several hours (ref sunburn)
▪
All above is also valid for people in your surrounding.
▪
Make sure air supply is sufficient, especially in small rooms.
▪
Never weld bottles, barrels or tubes that contained inflammable liquids or gasses, even
after a long time residues can cause explosions.
▪
In an environment with fire / explosion caution, more strict prescriptions are valid.
▪
Welds that have to bear heavy tension or meet specific safety expectations must be made
by qualified welders.
▪
Remark: always make sure you connect the earth clamp to proper earth. In case you
don’t, severe damage may occur to main grounding or machine itself (melting of ground
wire).
▪
Mains socket must be secured with proper (automatic) fuses. (According to section of
wire, a standard socket with earth should have a 16A fuse) Using higher fuses may result
in burning of the wires and result in fire in the building.
6.2
Small and moist rooms.
When you use your welder in small or moist rooms you have to use extra insulation layers,
use high quality insulating gloves, leather or other very bad conducting material, to protect
your body. In extreme situation the output voltage may not be higher than 48V.
6.3
Protective gear
▪
While performing work, the entire body of the welder must be protected with clothing and
facial protection gear against radiation (burns).
▪
Welding gloves made of a suitable material (leather) must be worn on both hands. These
must be in perfect condition.
▪
In order to protect clothing/skin from flying sparks and burns, appropriate aprons must be
worn. If the nature of the work, e.g. overhand welding, requires it, a protective suit as well
as a safety helmet must be worn.
