That's _their_ problem. Complain to a TV station's investigative
reporter that they are trying to force you to offshore all of the jobs
at your factory. It'll make a great news story.


But my solution is BETTER! The electric company says that a projection
welder takes a huge slurp of power but only for a fraction of a second.
The billable KWH are almost nill and they would charge 20K to run a
new line and a monthly minimum.

I seem to recall that there were such welders that delivered the pulse
from a large capacitor, thus smoothing out the surges.

A motor generator set with large flywheel could also help.

Yea, there are ways to do it with a welder...but look at the link for
the swaging process...it's pretty cool.

I did look, and yes it's pretty cool. Spot welds take less space and
are probably stronger, but the swaged pegs would work well for many
things.

I too would prefer a big-assed projection welder. I do have a spot
welder that we use for sandwiching .62-.42-.62 parts for knot wheels.
