My Century Mig welder don't work right no more. There's an industrial online
auction nearby with several offers. A sampling is listed below. Could you
folks help me pick two or three to bid on? I don't want to hook up 3 phase
to weld, will any of the welders in group 1. run on single phase?
Any of these especially good for AL?
1. three phase welders
Miller model CP-300 Mig Welder, constant voltage DC arc welding power
source, serial #JH318213, 230/460V, 33/16.5 amps, 3 phase, 300 amp output,
100% duty cycle. Millermatic S-52D, 115V wire feed, serial #JE827842.
Includes partial spool of .030 wire. Cart mounted.
Miller CP-200 Mig Welder, serial #JE761708, 100% duty cycle. Millermatic
S-52A 115V constant speed wire feeder, serial #KA883413. Cart mounted,
includes spool of .035 wire.
Miller model CP-2VS Mig Welder, constant potential DC Welder continuously
variable slope, serial #U474120, 230/460V, 21/10.5 amps, 3 phase, 100% duty
cycle, 200 amp rated output. Millermatic 10A wire feed. Cart mounted.
2. 3 and 1 phase units. These two look to be going higher:
Miller Maxtron 450 CC/CV DC inverter Arc Welder, serial #KE561030, 230/460V,
phase 1 & 3, 450 amps rated output, 100% duty cycle Miller SR Control
extended reach wire feeder, serial #LC705426.
Miller SMT 304 CC/CV Arc Welder, 300 amp rated output 60% duty cycle with
Miller XR Control Extended Reach Wire Feeder on Bernard Teta Boom and cart,
59" x 67" x 95". Bring help and equipment for safe removal.
3. 3 phase power units. This one is real cheap, no wire feeder.(I have one
on a shelf)
Miller Deltaweld 451, constant voltage, DC arc welding power source, serial
#KK888649, 230/460V, 70/35 amps, 3 phase, 450 amps rated output, 100% duty
P.S. Many large lots of steel at this auction tht I'm sure will go cheap.
I've got too much. If anybody in MN wants a deal go to k-bid.com
304's are also not as reliable as 300's, according to some things that
I read. (but they are usually a lot newer).
I would personally say, all of the other welders are good. Place low
bids on all of them, win some, sell some, keep the best one.
Though I have a MIG welder (Millermatic 251) I remain a stick guy at
heart. I might even sell the 251.
If you dont get what you want, Ive got a very very NICE Airco PhaseArc
350 Mig, (3ph)..300 amp out, with a nearly new Tweeco #4 gun on it that
Id sell to someone for...hummm to this group only..$800.
Thing looks nearly new and runs wire very very well. On a cart of
Cost a lot to get 3 phase for a welder. Probably not able to use a
converter. I have a Lincoln 180C. Came with a spool gun for aluminum, and
works well on up to maybe 5/16 thick. thicker you have to torch heat the
chunk to get decent welds. Does nice wire feed. I have only used flux core
in it, but looking to add another bottle(s) for welding stainless and carbon
steel. 220v single phase. Cost was about $1100 with a new empty bottle.
Probably cheaper now. Indiana Oxygen was the seller. Free shipping.
My Dayton 230 amp (Century) has had fan motors fail, feed potentiometers
fail and the gun had to be replaced. BUT, I can still get all the parts for
it and it has performed flawlessly for 20 years, except when it was broken.
Can't you repair the Century to do the same? It you have a little
What's the problem?
Its a little homeowner grade (S@#t). The wire feed gets bucky at
unpredicatable times. Just enough to keep the arc length constantly changing
on ya. Replace everything and it works a while, then when you really need it
and don't have time to fart around, it screws up again.
I had to change the roll up door track on my shop bay door recently. So
I dragged out my little Lincoln Weldpak 100 for the job. 110vts, has
been absolutel trouble free for years. Im in a hurry, need to go down to
LA for a service call. So I fire up the welder..and it welds for a
couple seconds..then quits.
Spool tension had backed off..the spool had unrolled about half of
itself inside the case, then jammed, burned out the liner, the short
piece of liner from the roller to the main liner and unrolled about 300
feet of flux core inside the machine. Damnit I hate it when that
happens. I had to pull a long extension cord, fire up the 220volt
DanMig, roll it from the welding area etc etc..took damned near an hour
to get it all ready..3 minutes to do the welding. Took another hour and
a half when I got back from LA to put everything back in place, and
another hour or two to modify a spare liner to fit, clean out the short
roller liner and get the Weldpac back in operation again.
All for a 3 minute welding job...sigh.

Yabbut, think how bad you'd feel if you had to call a welder out for
that 3 minute weld. Count your blessings that A) You could do the
weld yourself, B) You own welders, and C) that you know how to and
have the parts to repair your own schtuff!
Yeah, it's a PITA, but it beats the alternatives.

to do and they will surprise you with their ingenuity.

Oh but of course!
Thats why I hang around here and Learn Stuff. Tools I got...perhaps far
far too many of them.
Course..if I didnt have tools..Id not have needed the roll up door in
the first place.....

So... Like computers, there is no such thing as a "quick fix"?
Or a short beer?
Or a quick trip to the store ...
