Introduction
Thank you for purchasing one of our products. Please read in-
structions 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 (IEC 60974-1)
84
The use of a welder is typically discontinuous, in that it is made
85
up of effective work periods (welding) and rest periods (for the
positioning of parts, the replacement of wire and underflushing
86
operations etc). This welding machine is dimensioned to supply
I
max nominal current (350 A), in complete safety, for a work
88-91
2
period amounting to (35%) of total usage time. The regulations
92
in force establish the total usage time to be 10 minutes. If the
permitted work cycle time is exceeded, an overheat cut-off oc-
93
curs to protect the components around the welder from dan-
gerous overheating. The yellow thermostat LED located on the
94
machine rack panel lights up when the overheating protection
trips. After several minutes the overheat cut-off rearms auto-
matically (yellow LED off) and the welder is ready for use again.
How to lift up the system
Before lifting the unit, open the bag containing the eyebolts (at-
tached to machine), remove the two eyebolts complete with fi-
bre washers and mount them on the upper part of the cover.
IMPORTANT: Only lift the unit using the two eyebolts.
The wire-feeder has a handle and a hook so that it can be
hung up.
NOTE: The lifting and transporting devices conform with Eu-
ropean regulations. Do not use other equipment to lift or trans-
port the feeder.
