Question

28-31

In GMA welding, the voltage is set and the amperage is set On the welder, on the welder by changing the wire-feed speed, on the welder On the welder, by changing the wire-feed speed by changing the wire-feed, by changing the wire-feed speed. Electrode wire has a natural curve that is known as its. curve cast diameter circle. The perpendicular welding gun angle produces welds that have more penetration and less reinforcement have a good balance between penetration and reinforcement have less penetration and more reinforcement are more likely to cause burnthrough than any other welding gun angle
