Particular danger
spots
Keep your hands, hair, clothing and tools well away from all moving parts, e.g.:
- fans
- toothed wheels, rollers, shafts
- wire-spools and welding wires
► Do not put your ngers anywhere near the rotating toothed wheels of the wirefeed
drive.
► Covers and sideguards may only be opened or removed for as long as is absolutely
necessary to carry out maintenance and repair work.
While the machine is in use:
► ensure that all the covers are closed and that all the sideguards are properly
mounted.
► and that all covers and sideguards are kept closed.
When the welding wire emerges from the torch, there is a high risk of injury (the wire
may pierce the welder’s hand, injure his face and eyes ...). For this reason, when feeder-
inching etc.,
► always hold the torch so that it is pointing away from your body (machines with wire-
feeder).
► wearing a pair of appropriate regulation goggles (with sideguards)
- Do not touch the workpiece during and after welding - risk of injury from burning!
- Allow welding torches - and other items of equipment that are used at high operating
temperatures - to cool down before doing any work on them.
- Special regulations apply to rooms at risk from re and/or explosion. Observe all rel-
evant national and international regulations.
- Power sources for use in spaces with increased electrical danger (e.g. boilers) must
be identied by the (for “safety”) mark. However, the power source should not be in
such rooms.
- Risk of scalding from accidental discharge of hot coolant. Before unplugging the con-
nectors for coolant forward ow and return ow, switch off the cooling unit.
- If a machine is tted with a carrying strap or carrying handle, remember that this strap
is ONLY to be used for lifting and carrying the machine by hand. The carrying strap
is NOT suitable for transporting the machine by crane, fork-lift truck or by any other
mechanical hoisting device
- Inspection interval and extent of testing have at least to comply with the relevant
national standards and guidelines.
- Danger of colourless and odourless inert gas escaping unnoticed, when using an
adapter for the inert gas protection. Seal the adapter thread for the inert gas connec-
tion using Teon tape before assembly.
The following requirements with regard to shielding gas quality must be met
if the welding system is to operate in a correct and safe manner:
- Size of solid matter particles <40μm
- Pressure dew point <-20°C
- Max. oil content <25mg/m³
Filters must be used if necessary.
NOTE! There is an increased risk of soiling if ring mains are being
used
