The welder i bought doesn't have drive rollers available for . 023. .030 is the smallest the 250 will run.
Don't know what type of welder you have. But You can get .023" rollers for a Miller 250. Doug
Eastwood elite 250 MPI, thier newest and most powerful at 250 amps/ 60%duty cycle. For the money, 1400$, i consider it a nice unit. Has Mig, Tig, stick, no scratch start. But it would be nice to have the Tig option for aluminum. They do sell a spool gun for $209.00 though. Also another nice option would be a pulse weld feature for things like headers, etc
Been said here many times. Silicon bronze rod or wire is used to braze metal. It is anot a strong weld joint at all since the brazing process is not meltng base metal.
Since we like youtube here ya go. Nice visual explanation.
