[TheForge] MIG Welding question

Thu Jul 25 16:53:47 2002

Hi Jeremy:

Welding thin wire to a flat surface isn't the easiest but isn't hard with
some practice.

Regardless I use this trick when I'm doing what you are:

1) Don't close the ring.

2) Hold the ring with the gap against the sq tubing.

3) Weld in the gap till puddle encloses the ends of the wire.

If it ain't forged
it ain't real.
Wrought iron is.
