If possible, the work piece should be positioned so that the bead will run on a flat surface. Preparing The Joint For effective welding, the surfaces to be joined must be free of dirt, rust, scale, oil or paint. Welding on metals not properly cleaned will cause a brittle and porous weld. If the base metal pieces to be joined are thick or heavy, it may be necessary to bevel the edges, with a metal grinder, at the point of contact, as shown below. The angle of the bevel should be approximately 60

Extension cord lengths longer than 25 feet will require heavier wire gauges to compensate for voltage losses. INSTALLING THE ELECTRODE HOLDER 2.6 Attach the electrode holder to the electrode cable according to the following steps. Remove the handle (3) from the electrode holder (1) by removing the 1. screw holding the handle (not shown) and sliding the handle off. Remove the screw (6) from the electrode holder (1). 2. Push the cable (4) through the handle (3). 3. Insert the screw (6) through the

Until the final conclusions of the research are reached, you may wish to minimize your exposure to electromagnetic fields when welding or cutting. To reduce magnetic fields in the workplace: • Keep cables close together by twisting or taping them. • Arrange cables to one side and away from you. • Do not coil or drape cables around your body. • Keep cutting power source and cables as far away from you as practical. • Connect work clamp to workpiece as close to the cut as possible.
