Final answer:
In Gas Metal Arc Welding (GMAW) and Flux-Cored Arc Welding (FCAW), increasing the wire feed rate raises the current in the welding circuit.
Step-by-step explanation:
The question relates to Gas Metal Arc Welding (GMAW) and Flux-Cored Arc Welding (FCAW), which are welding processes that utilize a continuous wire feed as a filler material. Increasing the wire feed rate in these welding processes increases the current in the welding circuit. This is because the current is directly related to the amount of wire that melts per unit of time; more wire requires more current to melt it.
