2-3. Volt-Ampere Curves

ssb1.1 10/91 – SB-144 925 / S-0700

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.
