RECOMMENDATIONS FOR USE

1. CUTTING CAPACITY
Cutting thickness in solid sheet: 12 mm
Thickness of quality cut: 20 mm
Separating cut: 30 mm
2. USING THE SET WITH AN EXTENSION CABLE
The maximum extension cable length that can be used with-
out affecting the set's cutting characteristics is 25 m and a
cross section of 2.5 mm2.
3. USE OF A TORCH MADE BY A COMPETITOR
WARNING: AIR LIQUIDE WELDING DECLINES ALL RE-
SPONSIBILITY SHOULD THE GENERATOR BE USED WITH A
TORCH OF ANY OTHER MAKE THAN AIR LIQUIDE WELD-
ING. SINCE THE VOLTAGES USED IN THE POWER SOURCE
REPRESENT A REAL DANGER TO THE OPERATOR, AIR LIQ-
UIDE WELDING MAY NOT BE HELD RESPONSIBLE FOR
ANY COMBINATION OF COMPONENTS NOT OF ITS OWN
MANUFACTURE.
4. USE WITH AN ELECTRICAL GENERATOR SET
If the generator set is powerful enough to feed the unit (max-
imum power consumption: 15 kVA) and if it has sufficiently
stable regulation (voltage: 230V ± 10% or 400V ± 10%), it
can be used to provide the power for the equipment cutting
unit.
5. POSITIONING THE TORCH
Striking at the edge of the sheet
Mid-sheet striking
When striking in the middle of the sheet, metal spatter can re-
bound onto the nozzle and damage it.
- To avoid this, position the torch in such a way as to eject
sputter to the side.
- Perform the cut leaving the striking point in the off-cut. Re-
lease the trigger to switch off the cutting arc.
