APPLICATION CONDITIONS

Clean the welding area from dirt and oxide film. Preheat the heavy parts. When connecting a thick metal with a thin piece, preheat a heavier piece. Welding is performed by using the upper portion of the amperage range. Feed the electrode quickly and move fast, maintaining a very close arc gap. Reduce the current while the welding is performed and as the base metal absorbs heat.
