BASIC WELDING
WELDING TIPS
SETUP
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, a welder with a 40% duty
cycle at 100 A welding current must be
allowed to rest for at least 6 minutes after
every 4 minutes of continuous welding.
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 Welder overheats, it automatically
shuts down and the Overload Indicator
lights. The Welder automatically returns to
service after cooling off. Should this occur,
rest the MIG Gun on an electrically non-
conductive, heat-proof surface, such as a
concrete slab, well clear of the ground clamp.
Allow the Welder to cool with the Power
Switch on, so that the internal Fan will help
cool the Welder.
When the Overload Indicator is no longer
lit and the Welder can be used again, use
shorter welding periods and longer rest
periods to prevent needless wear.
