E70T-1
The downhand version of the rutile flux cored family, trading position capability for a larger, more fluid puddle and higher deposition rate in the flat.
What the designation means
Point at any character to see what it claims. The classification is a sentence written in fields, not a product name.
- EElectrode carrying the welding current.
- 770,000 psi minimum tensile strength of the deposited weld metal.
- 0Restricted to the flat position and horizontal fillets rather than all positions.
- TTubular flux cored wire.
- -1The usability class: a rutile flux requiring external shielding gas, run on direct current electrode positive.

Typical uses
- High volume flat groove welds on heavy plate
- Horizontal fillet welding in a shop with the work positioned
- Shipyard and heavy fabrication panel lines
How it runs
- Higher deposition rate than the all-position version of the same family
- Large, fluid puddle that will run if taken out of the downhand position
- Heavy slag that lifts cleanly and leaves a smooth bead
- Smooth spray-like transfer with low spatter
Storage and handling
Store spools sealed with desiccant and rebag partly used spools; flux cored wire absorbs moisture from shop air quickly.
Compare with
FCAWE71T-1The dominant gas shielded flux cored wire for structural work, giving high deposition with a fast freezing slag that holds the puddle for vertical up welding.FCAWE71T-8A self-shielded flux cored wire that needs no gas bottle, combining all position capability with the low temperature impact toughness structural codes ask for.SMAWE7024A heavy iron powder production rod that is dragged along the joint on its covering, laying long flat fillets faster than any all-position carbon steel electrode.
