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.
