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 replace-
ment of wire and underflushing operations etc. This
welder is dimensioned to supply a 150 A (series 150)
and 170 A (series 170) nominal current in complete
safety for a period of work 25% (series 170) or 45%
(series 150) of the total usage time. The regulations in
force establish the total usage time to be 10 minutes.
The 30% work cycle is considered to be 3 minute of
the ten-minute period of time.
