What do you guys charge for cadwelding. I don't any unit pricing on my program. Also what is the best caldweld unit to buy?
i'm partial to erico, both for the molds and the weld material.
there's some erico knock off stuff in similar packaging that works
well, and some really cheap stuff in foil pouches that you want to
avoid like the plague. for all around best results.... erico.
the best source i've found for all things grounding is mayday grounding.
burndy and erico are their primary lines. they also do lightening
rods, arresters and whatnot. they are in buena park, calif.
they ship everywhere.

their on site inventory of blocks, handles, and shot is larger than erico's
factory inventory.
i don't use the prepackaged electrically fired shots for a number of
reasons. cost is significantly higher, and with the smaller size shots,
sometimes the mold material will need a little more to get a good fill,
and i'll keep two size shots on the truck, and use them for smaller molds
by just dumping the extra. otherwise, you end up with half a dozen
different size shots, and you end up out of the one you need, so you
end up dumping anyway....
molds? avoid crosses. two tee's are a bunch faster than a cross, and
the molds are WAY cheaper. keep in mind that if you are doing cadweld
for poco's, they sometimes have a spec. that you cannot have two
cadwelds within 18" or 2' of each other.
mold consumption is a major variable. depends on who is doing your
cadwelding. i've watched guys scrub molds with wire brushes between
shots. it ruins the molds. erico says mold life is 50 shots. i get beween
200-300 shots from a 500 mcm tee. no scraping tools or wire brushes
in the mold throat or cavity.
you asked about pricing... for little stuff #6 - #2, i charge $25 a shot
plus my hourly rate. if it's not a mold i have, the mold, handle, shots etc.
plus 25% markup. so 500 mcm tees, i'd say about $50 a shot for material,
plus the labor rate.
someone else mentioned a price of $200 - $700 a shot....
seems awfully high to me..... how do i get work like that?
