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. http://www.halversoncts.com/79-arc-welding-power-sources-for-gmaw-and-fcaw.html
