When possible, set the shielding gas flow rate on GMA, GTA, and ____ welding processes at the lower end of the flow rate range to reduce the shielding gas cost.
A) FCA
B) GFCI
C) FOW
D) EPA

Question

Quizplus · Accepted Answer

GMA (Gas Metal Arc), GTA (Gas Tungsten Arc), and FCA (Flux Cored Arc) welding processes all require a shielding gas flow rate to protect the weld area from atmospheric contamination. When possible, setting the flow rate at the lower end of the range will help reduce the consumption and cost of the shielding gas, while still providing adequate protection for the weld. GFCI (Ground Fault Circuit Interrupter) and FOW (Flow Obstruction Warning) are not related to welding and EPA (Environmental Protection Agency) is an organization, not a welding process.
