High Strength, Low Alloy MIG Wire
MigTectic 80 ®
WIRE • Used on problem steels containing high sulphur content • Excellent arc stability and increased porosity control • Produces radiographic quality welds • Excellent impact resistance and high tensile strength
DESCRIPTION:
PROCEDURE FOR USE:
MigTectic 80 is a low-alloy wire designed to produce high strength on a wide range of base metals such as problem steels containing high sulfur, sometimes encountered with carbon and low alloy Cr-Mo base metals. Its higher silicon level, with molybdenum and manganese, provides excellent arc stability and increased porosity control when welding with CO2 gas. MigTectic 80 also offers low spatter, yielding a flat bead with excellent impact values and high tensile strengths in the 80 to 90 ksi range. MigTectic 80 produces radiographic quality and porosity- free welds, even on poorly cleaned base metals.
Preparation: Clean weld area of scale and/or oxide. Check that the ground clamp is secure and in contact with a clean surface. Make sure all joints on thin gauge metals are tightly abutted with no gaps. Note: Backing strips are useful in preventing burn-through. Technique: Be sure that the contact tip, gas diffuser, gas cup, & wire-drive rolls are suitable for the wire diameter and arc mode. Make a few practice runs to refine and optimize the Guideline Parameters. Post-welding: Allow parts to slow cool in still air.

HEALTH AND SAFETY:
Operating Conditions:
Observe normal welding practices, respiratory protection and proper air flow pattern advised. For general welding practices, see AWS publications Z49.1 “Safety in Welding and Cutting and Allied Process”. Welding is a completely safe process when performed in accordance with proper safety measures. Become familiar with local safety regulations before beginning welding operations. DO NOT operate welding equipment or use welding materials before you have thoroughly read the proper instruction manual(s).
