ARC Welding Technique FOR BEGINNERS A Word To Beginners Striking An Arc For those who have not yet done any welding, the simplest way to Practice this on a piece of scrap plate before going on to more commence is to run beads on a piece of scrap plate. Use a mild exacting work.
Installation AND OPERATION Make sure that the supply voltage matches the voltage requirements indicated. (15% deviation is allowed) If you increase the length of the leads, be aware that possible damage may occur with excessively long leads. - Ground the unit with a minimum of 6mm² (10 gauge) wire to the earth ground as the drawing. - Connect the earth lead connector to the negative (-) quick-connection terminal, and turn clockwise to tighten.

Joint Preparation In many cases, It will be possible to weld steel sections without any special preparation. For heavier sections and for repair work on castings, etc, it will be necessary to cut or grind an angle between the pieces being joined to ensure proper penetration of the weld metal and to produce structurally sound joints.
