Welder price guess

[Bill G]

You got took

Well I dug back and I was wrong the new price was $11,000. Here is where I listed it on this great site.

SELLING - Lincoln Invertec SST II MIG welder

Hello, I have a Lincoln Invertec SST II welder and feeder that needs a home better suited for the machine capabilities. This is a high end unit that is in all honesty was too high end and Lincoln no longer sells it here in the USA but still does in Europe. It lists for around $11,000 which is...

I sold a Lincoln that was $12,000 new for $300 and change because it was a dedicated 3 phase and no one was bright enough to run it.

All you doubters I have the receipts.

3 phase machines go for the biggest discounts. Common knowledge.

Things are only worth what someone is willing to pay for them.

The bigger machines, even the single phase, require a lot of power input and generally a dedicated circuit. My Syncrowave 250 had power factor correction and drew 80 amps at idle. My regular Nema 50a outlet wasn’t enough for it, so I had to remove the PFC cans. Even then, I was maxed out at 210 amps.

My inverter can go 300 amps all day on 220V 50a. That’s the difference. The above welder is a machine that’s way more versatile. I wouldn’t be surprised if it goes for over 3k. More power to the buyer if he gets a discount.

Yup. That's it. I remember it being oddly tall.

Yep, that’s it. Fantastic machine that I would buy if I had the space and power. Actually came equipt with garden hose barbs for water in/out and a solenoid for the water. It’s set up for water cooled torches.

It’s a sine wave machine and has a wonderful arc. When I began to TIG weld, I was like the others. I thought it wasn’t me, it was the machine that caused my welds to be terrible. You come to realize that it’s 95% Indian and 5% arrow.

I had a Dynasty 200 tig runner package. I sold it when I found a new Sanrex (Japanese) TA300 Arcmaster. Squarewave without the endless options of the Dynasty. My buddy recently got a Dynasty 400 which is the Caddy of Tig machines for Aluminum. I didn’t think it was any better than my current machine at my skill level.

After all the hoopla, I like 35% cleaning and 60Hz, same as the old sine wave machines.

The amp draw is irrelevant.
Yes 3/0 is a downside but in all the years I have yet to see a MODERN welder that was not able to be jumpered to 1/0.
I have multiple rotary converters and I am well versed in running 3/0 equipment.

Correct. Modern Millers are all multi voltage and phase.

I considered a converter at one point. The machines can be had at huge discounts.

Amp draw is relevant for a guy with a Home shop and a 200 amp house service, like I have. It isn’t cheap to run a new sub panel, especially with the cost of copper wire these days.

I considered a Miller 300 mig, but it’s the same as the 250 but is 3 phase. I do not believe it was able to be run on 1/0, I could be wrong.

I run an XMT304CC/CV with a 12” remote voltage suitcase as my mig setup. If it weren’t for Aluminum, I’d add a HF box and call it quits.

I do have a spoolmatic 30a and an optima pulser for aluminum, but I’ve never used it once. Someone could have a deal on that if they wanted.

Same as with very big lathes. Generally go for huge discounts because not many have the room, power, or ability to move the damn things.

In general lathes do not require a very high amp draw and are relatively easy to run on a rotary converter. That is because the have small electric motors. Most of the old 10x24 and 12x36 lathes only had 3/4 to 1hp motors. Hell my neighbors Shipley was a jackshaft machine. Shucks a 9x42 Bridgeport has about that size motor on it.

Go try firing up a 4 head moulder with a 4 motors totally around 45hp. I will never forget the day the power guy showed up.

We are on 1940's 7200V lines yet.

I've got a 3 phase rectifier DC machine ,400 amp Westinghouse I rewired for single phase .It was originally an open delta which I stacked up parallel


and used a double Pi filter to take the ripple out of .It's probabley 225 amps now and smooth as silk .

 

[Al Smith]

Now about rotary phase converters people think are black magic which they are not .They are just a three phase motor using one winding as a start winding with a couple of capaciters .I've lost track of how many I've built .My shop uses a 5 HP .Then again my set up is rather odd .In addtion to 120-240 single I've got 240 three phase,480 three phase, 277 single and 208/365 three phase .Give me enough transformers I could build a bolt of lightning .

They are not black magic but if you or others want to think so great. I have known folks to "kick start" them.

They put out a video yesterday, showing again the HUGE amount of tools that need to be sold and much of it is business/shop stuff. Not at all for cookie jar, cheap toaster garage sale junkies. Perhaps telling, 12 hours and only 44 views.

 

[Al Smith]

Problem with that deal is no run caps causing them to run hot with one phase about on a 15- 20 degree lag on generated voltage .Rule of thumb on 240 volt is 7.5 micofarad per HP .Generated voltage too high , less capacitance too low more of same . Mine of course is 480 volt by use of transformers and is about 5 volts above or below 480 volts .Just so you know I never thought it was "black magic " rememmber what I did to make a living .Over 50 years first was a sonar tech,four years on nuke subs, 20 years IBEW journeyman inside wire man , 29 years Ford Motor company ending up working on robotics and CNC machinery . So to speak it's not my first rodeo .

 

[Al Smith]

Since it's migrated to phase converters another thought .Using the same start circuit you can single phase a three phase motor to use as a power source but it only produces about 59 percent of the motor rating .In other words ten HP has about 5.9 HP usable .Name plate rating divided by 1.7.Keep in mind you are only paying power for 5.9 not the full 10 HP .Same with an inverter which if figured it out is much more effective than a big single phase motor plus doesn't cost a kings ransom like a large single phase motor which you can find in a salvage yard for pennies on the dollar .

 

[Bill G]

The general rule is they will run three times the start. A 10hp will start one 10hp and run 30 total HP.

Of course that does not apply to welders.

 

[Bill G]

Same as with very big lathes. Generally go for huge discounts because not many have the room, power, or ability to move the damn things.

We have a military installation here that does all types of manufacturing and repairs. It is just called "The Arsenal" and sits on a 1000 acre island. During WW2 I believe they employed around 12,000 but are now down to 6000. Of course being the government they make bad decisions. They routinely sell off equipment that they have not used in a certain period of time but will need again. .....idiots!. About 20 years ago we went over on auction inspection day to look at some 600 amp Miller machines and a small CNC screw machine. While we were walking through the rows of equipment I spotted a large lathe. Of course this is post 2001 so we had to be escorted by a guide. He said it was used to maintain naval gun barrels but since it had not been used in a while it got the "tag of death" to be sold. It had a 20ft bed and about a 6 ft swing. That was the largest I had seen since I was in the Gleaner combine factory in 1988. I wonder where it ended up.

 

[Al Smith]

I've seen some monster lathes .After I got out of HS I was a welder at Baldwin -Lima- Hamiton once made huge steam locomotives .The largest was a shaft lathe at NewPort News ship building and dry dock when I was in the navy .That thing turned shafts for aircraft carriers .

 

[Al Smith]

Back to welders,I've got an odd ball ,P and H motor generater 300 amp DC .It has I think a 12 HP three phase AC motor swinging the generater .However it also has a stub shaft with a flat pulley you could use the machine for a power source or belt it to a tractor as a power source for the welder .I'll snap a picture the next time I go to my shop
Might add I also have a SA 200 Lincoln,Continental flat head engine driven plus a Hobart main line special 250 amp engine driven with a Jeep engine .Those came with a deal that included an Onan army signal corps field generater circa WW2 with about any voltage you could think about depending on where you wired the jumpers . That thing is large enough I could run anything in my house plus the ac and most likely have enough to run a buzz box welder .Pot licker can suck down about 3.5 - 4 gallons of gasoline per hour to do that which is why it sits .

 

[Bill G]

Sale starts Thursday.

Well it is only a few hours till it starts. Hopefully you have some good news.

 

[OnlyStihl]

Might be just my imagination, or my excitement, but I feel this is going to be a huge turnout. I've a list of 10 big items I'm looking to check out. Many of which I'd have to leave a deposit and comeback for with my trailer. Or maybe I get nothing. I'm certainly going to pick out 1 of the 80 cookie jars on sale to bring home.

Web site says the present owners are leaving with only a suitcase. Wow! Fugitives?

Aaahhh yessss I remember using one of those for about 4years!! Great DC arc stability..A\C yuk! Had to adjust the spark gap just right inside the machine with feeler guage ..I was working at a mold shop that also proved their molds with a foundry onsite, and I did a bunch of aluminum casting repairs. I finally sold the purchasing guy on getting me a Dynasty, and casting repair was a breeze after that..
