* This chart is only intended to show general guidelines for different wire sizes and for different
thicknesses of material. The settings should only be used at the beginning of a weld and must be
adjusted after stopping and carefully inspecting the weld. Proper welding takes experience.
Duty Cycle (Duration of Use)
Avoid damage to the Welder by not welding
for more than the prescribed duty cycle time.
The Duty Cycle defines the number of minutes, within
a 10 minute period, during which a given welder can
produce a particular welding current without overheating.
For example, this Welder with a 20% duty cycle at
rated output (90A) must be allowed to rest for at
least 8 minutes after every 2 minutes of continuous weld.
Failure to carefully observe duty cycle limitations
can easily over-stress a welder’s power generation
system contributing to premature welder failure.
This welder has an internal thermal protection
system to help prevent this sort of over-stress.
When the unit overheats, it automatically shuts down and
the Overload Indicator lights. The welder automatically
returns to service after cooling off. Rest the Gun on
an electrically non-conductive, heat-proof surface,
such as a concrete slab, well clear of the ground clamp
while allowing the welder to cool with the Power Switch
on, so that the internal Fan will help cool the welder.
When the welder can be used again, use shorter welding
periods and longer rest periods to prevent needless wear.
