Workpiece clamp
If the electric flex of the workpiece clamp is shorter than
the torch hose pack or the manual electrode cable -
meaning that the clamp cannot be fixed anywhere
immediately near the welding zone - then the welding
current will find its own way back. It may do this via
machine parts (e.g. during repair work), ball-bearings,
electric switches etc. This may then cause certain parts
to become red-hot, make chains and steel cables snap,
and even cause the PE conductor to melt through.
All this can also happen if the workpiece clamp has
simply not been fastened properly, or only laid on the
surface of the workpiece, in which case the course taken
by the current will depend on the presence of “bridges”
or angle bars and the like (Fig. 1).
Personal protection
o
As a basic safeguard, insulating gloves should be
worn on both hands when welding. These protect
against electric shocks (from the open circuit voltage
of the welding current circuit), harmful rays (heat and
ultra-violet rays), and against splashes of red-hot
metal or slag.
o
Solid, insulating footwear should be worn, which
should also insulate the wearer in wet conditions.
Ordinary shoes are not suitable as falling globules of
molten metal can cause burns.
o
Suitable clothing must be worn - NO synthetics!
o
Do not look at the arc with unprotected eyes. Use
only protective welding shields with the prescribed
type of safety glass. As well as heat and light rays,
which may cause dazzling or burns, the arc also gives
off ultra-violet rays. These are invisible, and if the
welder is insufficiently protected against them they
can cause conjunctivitis, which only makes itself felt
several hours later and is extremely painful. Quite
apart from this, ultra-violet rays have the same effect
as sun-burn on unprotected parts of the body.
o
Welder´s mates or persons in the immediate vicinity
of the arc must also be made aware of the danger
and provided with the necessary protective appa-
ratus; if necessary, protective screens must be
erected.
o
Care must always be taken to provide sufficient fresh
air, especially when welding in enclosed spaces,
since smoke and harmful gases are produced during
the welding process.
o
Containers which have been used to store gas, fuel,
mineral oils or other such substances must not be
welded, even if they have been standing empty for a
long time, since there is a high risk of explosion from
any residue.
o
Special regulations apply to enclosed spaces where
there is a danger of explosion.
o
Welds which are exposed to heavy stresses and
which have to fulfil strict safety requirements must
only be performed by particularly well-trained and
experienced welders. Examples include things such
as pressurised containers, track rails, trailer couplings
etc.
Fig. 1: Power source may never stand on electrically
conductive ground!
Connection to workpiece: NEVER like this!
Use a firmly connected clamp.
PE conductors will be destroyed if the welding
current ever has to find its own way back.
