Spoolarc
86 (AWS
Class ER70S-6)
- Spoolarc 86 is a copper plated gas-metal
arc welding wire. Containing
a high level of deoxidizers, it produces sound welds in all carbon
steels using CO2
shielding gas, argon/CO2 and argon/O2
mixtures. The arc is quiet and very stable.
High speed, high deposition welds can be made with argon-oxygen gas mixtures.
Ideal for welding sheet metal where
smooth weld beads with good wetting action are desir- able.
It may be used to weld carbon steels that have a moderate amount of rust
or mill scale. Spoolarc
86 can also be used for out-of-position welding with the short-circuit transfer
method, making
it ideal for pipe welding. Other applications are for bridges, building
construction, boiler
and pressure vessels, storage tanks, auto parts, and construction equipment.

Spoolarc
87HP (AWS
Class ER70S-7)
- Spoolarc 87HP is a high manganese
carbon steel wire. It features
an optimized manganese to silicon ratio to produce excellent
appearing welds over a wide range of
welding parameters. It also produces excellent weld
metal mechanical properties and welds
over moderate amounts of rust and scale. A.
