Hard Facing

[Bob]

Basic concept seems straight forward, but I got confused by the many different wire types listed under Hobart Products: one pass, multiple pass, impact, abrasion, or both, self shielding vs gas.

The intended victum is a sears leaf shreader shown in the picture. In the photo the top is folded away from the base to show the blade. Upright, it is like a beefy rotary mower with a top feed shute.

The tool in a HH-135, have 0.30 tips and argon for aluminum but the CO2 bottle and gas are still on my wish list.

I would like to put on shaper harder edges hoping to deal better with small branches. It does have to stand an occasional rock the gets raked up with the leaves.

Local hardware (and internet sites I have checked so far) don't even have any facing wire.

I am looking for a recommendation on the wire and a source.

Also, best techniques:
Should I quench it after weld, or wait until after grinding the edge.
How do I avoid the puddle "falling off the edge" ... sorta like off the side burn through?

The blade will be off the machine and I plan to check balance when done.
