There are a lot of youtube videos that show how to weld Mf.

Too many amps and the puddle will be excessively fluid and hard to control , excess spatter and higher potential for undercut.

If your amperage is too low, your electrode will be especially sticky when striking an arc, your arc will keep going out while maintaining the correct arc length or the arc will stutter.

Some easier rods to learn welding, would be Austarc rods.

I've been meaning to weld an old wheel brace back together for years now , finally got to it today and used some stainless arc rods ,
I thought it might snap in half again after welding as it might have weakened the hardened steel but tried the wheel brace on a trailer wheel
and seemed to have no problems.

I'd like to try some alloy arc rods on a alloy mower base as I've never tried welding alloy before.]

Cheers
Max.
