Harris Super Missileweld Welding Electrode 00SMW500POP

Harris® Super Missileweld Welding Electrode 00SMW500POP

18 Stick Tube - Harris® Super Missileweld stick welding electrode is a steel alloy electrode that can be used for welding virtually all types of mild steel, alloy steel and stainless steel. Super Missileweld is ideal when the exact alloy to be welded is unknown. It produces high-strength, crack-free welds on high carbon steels, tool steels, stainless steels; spring steels, manganese steels, and dissimilar steels. It operates on both AC and DC welding current, reverse polarity. Super Missileweld is the only stick welding electrode you need in your tool box.

NOTE: 3/32" diameter has 18 electrodes per tube. 1/8" diameter has 10 electrodes per tube.

Procedure:
Use either AC or DC reverse polarity
Clean weld area
Bevel heavy sections
For high carbon steels, a preheat of 400 F is recommended
Hold a short arc
Run stringer beads
Peening will help relieve stresses
Let each pass cool and slag will peel off easily
