Introduction
Thank you for purchasing one of our products. Please read
instructions on use in this manual as well as the safety rules
given in the attached booklet and follow them carefully to get
the best performance from the plant and be sure that the parts
have the longest service life possible. In the interest of custom-
ers, you are recommended to have maintenance and, where
necessary, repairs carried out by the workshops of our service
organisation, since they have suitable equipment and specially
trained personnel available. All our machinery and systems are
subject to continual development. We must therefore reserve
the right to modify their construction and properties.

Usage limits (ISO/IEC 60974-1)
The use of a welder is typically discontinuous, in that it is made
up of effective work periods (welding) and rest periods (for the
positioning of parts, the replacement of wire and underflushing
operations etc). This welding machine is dimensioned to sup-
ply I
max nominal current (200 A), in complete safety, for a
2
work period amounting to (25%) of total usage time. The regu-
lations in force establish the total usage time to be 10 minutes.
If the permitted work cycle time is exceeded, an overheat cut-
off occurs to protect the components around the welder from
dangerous overheating. Heat protection activation is indicated
by a yellow warning light on the thermostat on the rack panel
of the machine. After several minutes the overheat cut-off
rearms automatically (and the yellow signal light turns itself off)
and the welder is ready for use again.
