What is Flux-Cored Arc Welding (FCAW)? – A Full Guide

WebFCAW imparts a higher production rate as it does not require changing electrodes periodically. The process generally uses direct current constant voltage types. Flux Cored … WebApr 30, 2024 · It is to be noted that the current is not perfectly constant. With variation in voltage, the current varies a little. In the processes that utilize a non-consumable electrode, the variation in voltage can occur due to variation in arc length. Some variation can occur because the hand cannot be held perfectly steady, and tends to shake a little. dr chitnavis roanoke va
