cOntrOlS POWER SWITCH (1). Use this selec- tor to turn the welder Off, or On to the correct Voltage. WARNING: It is imperative that you select ONLY the Voltage setting for which you have wired the Power Cable. POWER CABLE (). You will have wired this for either 115 or 30 Volts. - Page 13 important information, you are strongly urged to obtain appropriate training, and to practice on non-critical test pieces before attempting to weld important items. To begin welding, first observe all safety precautions, then attach the Ground Clamp to the workpiece in such a way as to provide good electrical conductivity between the weld area and the ground clamp.
- Page 14 troubleshooting Arc Welding defects porosity and Surface Holes Most porosity cannot be seen, but serious porosity weakens the weld. Before welding, remove all surface contaminants, such as Mill Scale, Rust, Paint, Dirt, Grease, or Moisture. Keep the weld puddle molten for a longer period, allowing time for gasses to escape. Steel with an extra low Manganese or Carbon content, or with a high percentage of Sulfur or Phosphorous will need to be welded using an E7018 rod.
