WELDING ELECTRODES LOW HYDROGEN NO.7018, 5KG PACKET, SIZE 3MM

Instructions: Use this electrode with DC+ (reverse polarity), however, an AC machine with sufficient open circuit voltage may be used. Clean the weld zone of all contaminants. Bevel thick sections to a 60° Vee and preheat at 300-500°F. Set amperage to the proper range as listed on the product recommended amperage chart. Maintain a short arc length and hold the electrode at a 15° angle into the direction of travel. Weaving technique is preferred, however, do not exceed 3 times the diameter of the electrode. Do not use the whipping technique as this will cause porosity in the weld deposit. Always allow high-carbon steels to cool slowly before removing the slag.
