2.3 Volt-Ampere Curves
ssb1.1 10/91 – SB-144 925-A / S-0700-A
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.
