WARNING!
During operation of the welding equipment welding splashes are to be expected! The
consequence may be injuries to the eyes or burns.
Therefore:
-
wear protective goggles
-
wear protective gloves
-
wear flame-retardant clothes
Danger of injury at sheet metal edges and danger of getting burnt at the parts to be wel-
ded!
Therefore:
-
wear protective gloves
CAUTION!
-
Danger of injury and of damage to property when operating the units outside a
switch cabinet or for purposes other than the intended use!
The units are designed to be installed in housings or switch cabinets and may only
be operated in such housings or cabinets with the door closed. The recognized
rules of electrical engineering must be observed.
-
Danger of injury and of damage to property through missing or false interpretation
of fault messages!
-
Danger of bruises through electrode movement!
All users, line designers, welding machine manufacturers and welding gun produ-
cers are obliged to connect the output signal of the Bosch weld timer which initiates
the electrode movement so that the applicable safety regulations are complied
with.
The risk of accidents can be considerably reduced by means of, e.g.,
-
two-handed start
-
fences
-
light barriers etc.
-
Systems without <Monitor contact> MC
(not available in all weld timers)
If <Monitor contact> MC is connected to +24 VDC, the [squeeze times] must be
selected long enough to permit optimal contact of the part to be welded prior to the
[weld time]. If the [squeeze times] are too short, the electrodes close during [weld
time]. This will cause strong welding splashes, resulting in damages to the elec-
trodes and the part to be welded!
