I have trolling motor batteries, which are "semi-deep cycle".

Damn, I too used the carbon rods from D cells. Were you spying on me? :-)

I`ve tried contacting "Go-Weld" with a question reguarding
wether their equipment can be used in the UK,
with no response.
Are they isolated for EU interference standards and do
they make a 240V Power Conditioner for use with the
mains supply (they do a 120V)?
Are there many similar products that could be listed here
that might be cheaper? So far, "Go-Weld" seems to be
the best buy although 400 for a little Plastic Pistol
(before buying the Batteries too) seems a bit steep to my
uninitiated Eyes (to welding equipment).

 It's been the better part of a 2 years since I saw the Go-Weld
demonstrated, but if I remember rightly, there was no AC power
connection at all. That was the whole intent of the machine; giving
one the freedom to weld at a place remote from the AC mains. The
batteries can be recharged by any automotive-type battery charger, or
by swapping them into a vehicle.

I doubt there is any provision to eliminate RF interference, and I
don't believe I've ever seen such on a welder. Being as it runs on
battery power, and has no AC line connection, it won't be able to put
noise on the line.

I agree with you that it's expensive. Their asking price is about
twice what I'd be willing to pay for a seldom-used tool.

Reminds me of when I was younger.. I used to "faux-weld" when I was
bored,I'd connect a big honkin capacitor to a 12V power supply,and use
a couple heavy alligator clip wires,and a "rod" of solder. Made some
nice sparks!
The trick was the big honkin capacitor,it just wasn't the same without
it.
I havn't seen the battery welder setups,but a "big-ass" capacitor
across the output might be helpful. I think I used to use about
30,000uf for "solder welding".Suitable caps can be found surplus for
fairly cheap.I can get big (50,000uf 50V) computer grade caps for
about $ around here at surplus places.A few of those in paralell
should help out. Maybe one of those car-stereo 1 Farad "stiffening"
caps,if you can find one cheap. ;-)
