2-3. Welding Gun Duty Cycle And Overheating

CAUTION
WELDING LONGER THAN RATED DUTY CYCLE can damage gun and void warranty.
•
Do not weld at rated load longer than shown below.
•
Using gasless flux cored wire reduces gun duty cycle.
Definition

Minutes
Duty Cycle is percentage of 10
minutes that gun can weld at
rated load without overheating.

1 Normal Volt-Ampere Curves
The volt-ampere curves show the
normal minimum and maximum
voltage and amperage output capa-
bilities of the welding power source.
Curves of other settings fall be-
tween the curves shown.
2 Overload Volt-Ampere Curves
When unit is used beyond capacity,
circuitry senses the overload and
shuts down unit output. Release
trigger and lower weld voltage set-
ting before trying to weld. This shut
down circuitry protects internal
circuits and parts from overload
damage.
