How is the amperage adjusted on an FCA welding machine?
A) By changing the voltage setting on the welder.
B) You move the welding lead from one amperage setting to the next amperage setting.
C) Changes in the wire feed speed automatically change the amperage.
D) The amperage is pre-set by the electrician and cannot be adjusted in the shop.

Question

Quizplus · Accepted Answer

In Flux-Cored Arc Welding (FCAW), the amperage is adjusted by changing the wire feed speed. As the speed increases, more current is needed to melt the wire, thereby increasing the amperage.
