hreads the proper electrode wire through portable welding gun.

Starts power supply to produce electric current.

Strikes (forms) arc which generates heat to melt and deposit metal from electrode to workpiece and join edges of work piece.

Manually guides electrode or gun along weld line, maintaining length of arc and speed of movement to form specified depth of fusion and bead, as judged from color of metal, sound of weld, and size of molten puddle.

Welds in flat, horizontal, vertical, or overhead positions.
