Mark,

I forgot to ask - in your opinion, is there significant differences between
the 220V and the 110V welders? I know that the 220V welders are rated for
something like 3/16" and the 110V welders are rated for 1/8", but I'm not
too sure how to relate that to real functionality. I believe that your spot
welder is 220V and that this has pleanty of power for all of my use thus
far. I see the Miller 110V welders on eBay all of the time but rarely the
220V welders.

What do you think?

Larry... I don't think that would work. A spot welder uses a much higher
current at a much lower voltage.... in the many hundreds of amps range.
Enough to heat a 5/8" solid copper bar VERY hot.

P.S. The equipment used to be mine.

Just a thought, you have that big Lincoln welder, is it possible to use
it
as a power source for a set of spot welder tongs? I realize that there
would have to be some circuitry in between the two but is such a device
commercially available or does the spot welder have to be its own
machine?

no neat sig line.

I have done a little sheet metal work and have really enjoyed it
(although
I'm still a novice). I have a friend who recently shut down his sign
business and sold me some of his sheet metal equipment. It is just
perfect
for my home shop:

* Di Acro 24" shear
* Di Acro 24" brake
* Di Acro 6" notcher
* Berkroy 24" rolls

All of the equipment is on stands/casters. I have to clean some of it
up
a
little, etc. , but in general, it's in good shape.

I have a question about the shear. If I plan on primarily working with
about 20 gage steel, what spacing should I put between the blades?
Also,
is there any literature showing how to maintain this equipment, like
how
to correctly sharpen the blades (angles, etc.), how to properly adjust
the
equipment, etc.? I have printed the manuals from the DiAcro web site,
but
the manuals don't have much on tool maintenance and adjustments.

Of course, with all of that equipment, I'm looking for a spot welder.
The
American brand is Miller, but there are a number of Miller knock-offs
coming from China (as sold at Harbor Freight). Is the Miller welder
made
in America? Is it significantly superior to the China versions? I'm
just
a
home hobbiest, yet I try to support American industry a much as
possible.
It's just that the price difference between the two welders is about
$300
and I haven't personally held the Miller welder.

What is your opinion of the Miller vs. the Chineese spot welders?

I'm just tickled pink with my purchase and look forward to honing my
skills. Please reply to my questions and thanks.

Dave
