AUTOCRAFT LW1-6 CIGWELD MIG A Higher Manganese / Silicon Wire for GMAW Welding of Mild & Low Alloy Steels. Designed for Use with CO2 and Argon Based Shielding Gases. Wide Range of Minispool, Handispool and Autopak Packaging Options Classifications: AWS/ ASME-SFA A5.18: ER70S-6. Description and Applications: Autocraft LW1-6 is a high quality copper coated welding wire suitable for the all positional Gas Metal Arc Welding ( GMAW) of mild and low alloy steels, used in general fabrication and structural work. The high quality copper coating ensures problem free feeding, smooth current pick-up and minimal contact tip wear. The higher silicon content of Autocraft LW1-6 ensures excellent operator appeal, improved fillet shape / side wall wash at weld toes and very low spatter levels important for welding light to medium gauge sheet and tubular steel sections. Fillet welds exhibit a mitre to slightly convex profile with an even and smooth contour. The higher Manganese / Silicon levels give improved weld metal deoxidation when welding steels with moderate amounts of rust or mill scale. Storage Recommendations: When held under the recommended storage conditions unopened packs of Autocraft LW1-6 wires are expected to remain in ‘ factory fresh’ condition for at least 12 months. For storage over 12 months or under adverse ( damp or high humidity) climatic conditions the use of heated weather proof store rooms/ cupboards/ containers maintained at 10-15° C above ambient temperature ( with a maximum of 40° C) and at a maximum humidity of 60% R.H. is recommended. Product should be stacked on racks or pallets clear of the floor and walls.
