Instructions: Use DC+ reverse polarity however an AC machine with sufficient open circuit voltage may be used. Bevel thick sections to a 60 Vee. Clean the weld zone of all contaminants. Preheating 300 series stainless steel is NOT required. The diameter of the electrode chosen should be equal to the thickness of the base metal. Use the lowest possible welding current or increase your welding speed in order to avoid overheating or distortion of the base metal. Overheating stainless steel can degrade the composition and corrosion resistant properties. The arc length should be kept as short as possible but do not touch the flux-coating of the electrode into the molten weld pool. Hold the electrode at a 15 angle into the direction of travel. Stringer beads should be used in the flat horizontal and overhead positions. The weaving technique should be used for vertical welding but not to exceed two to three times the diameter of the electrode. Remove all slag before making additional passes. On the final pass allow the part to cool down partially before removing the slag then promote rapid cooling by quenching with a wet rag or compressed air. This will preserve the corrosion resistant properties of the 300 series stainless. Do not allow to slow cool.
