Fires And Explosions - Car-O-Liner CTR12000 Instruction Manual

CTR12000
The Spot Welder CTR 12000 uses high currents to heat the welding point. This current is supplied by the transformer
through the C-arm to the welding point. The current creates electro-magnetic fields (EMF) around the C-arm and the
transformer.
Exposure to high levels of EMF may be harmful and to reduce the exposure to acceptable levels the user of the welding
gun should keep a minimum distance from the head and trunk to the transformer and C-arm during welding as follows:
When using the C40 arm the distance to the C-arm should be at least 500 mm and to the transformer at least 300 mm.
When using the C500 arm the distance should be at least 600 mm and to the transformer at least 450 mm.

Fires and explosions

41643, ENG - rev. 2, 2016-10

shielding, where necessary, cables, leads and electric equipment in
the vicinity of the welding workplace
There are various sources possibly causing fire: Flying sparks spatters of
molten metal bath, hot slag, red hot pieces, thermal conduction or radiation,
short circuit, etc. and if explosive liquids, dust, vapour or gases are also in-
volved, deflagrations and explosions may be the result.
It is important and necessary to eliminate possible fire sources already before
the machine start and to take suitable precautions

If possible, do not perform welding in areas with increased fire risk!

If welding cannot be avoided in dangerous areas, remove all highly
inflammableor explosive substances (such as fuels, gases, dust,
inflammable liquids) from the workplace!

If this is not possible, cut off combustible materials by appropriate
covers, guards or similar devices!

Before starting any welding and cutting operation on empty
containers, check in any case whether they have held fuels, greases,
solvents or other highly inflammable or explosive substance! If
required, clean and ventilate the container thoroughly! Even small
traces of these substances left in the containers are a major risk of
explosion!

Do not cover the ventilating slits of the power source. Insufficient
ventilation and aeration may cause overheating.

Remove any highly inflammable objects such as matches or lighters
from your working clothes.

Tightly connect the workpiece clamp to the workpiece or the
welding bench before starting the welding process (stray welding
currents may damage the protective conductor systems and cause
fires)!

During welding, pay always attention to sources of fires!
