Why do those old LINCOLN welders have such a good arc

admin

Wondering why do those old Lincoln portable stick welders weld so good.Example 8010..I have tried 8010 with a Pipe Pro and also  a  from the fifties Lincoln.The lincoln  won hands down.How come Lincoln doesn't build them like that anymore??

Reply:I dont know that the copper has as much to do with it. I think the fact that they are generating DC, and not rectifying A/C plays a bigger role. I also think the lore makes them pump out creamier, smoother DC than is possible to have. I have welded with a lot of different machines from the shop Lincoln generators, to the SAEs, TBs, Tombstones, XMT304, Syncrowave, etc. A lot of them put out a very nice arc, are easy to weld with, I had no issues. When I have had issues it was generally found to be a particular batch of rod, a poor connection, or poor power input. Get rid of those variables and machine performance improves.
Reply:If they are generating DC they are still making AC and mechanically rectifying it with commutator and brushes. In the old days they weren't being stingy with the copper you get bigger fatter inductors.old Miller spectrum 625 Lincoln SP-135 T, CO2+0.025 wireMiller model 250 and WP-18V torchCraftsman 100amp AC/DC and WP-17V torchCentury 115-004 HF arc stabilizerHome made 4 transformer spot welderHome made alternator welder
Reply:They used generators instead of alternators for making the electricity. Much smoother.
Reply:An older guy who owned a older Lincoln told me  the older Lincoln welders had 102 OCVs (not that I know anything about OCVs) and it is not lawful to make welders with so many OCVs anymore..Anybody know anything about that?

Reply:A DC OCV is far less dangerous than AC.
Reply:Less dangerous, but the key word is less. It's still dangerous. A 9V battery can kill you if you get good contact with the conductors. The higher the voltage, the higher the current across you if you bridge the poles, and the better it conducts through poor conductors such as skin and cloth.
Reply:I like this videoPay attention at 10:00, 14:00 and 30:00 for DC generator

Reply:Originally Posted by BlueweldersOk,so actually there is no safe voltage if things go wrong.

Reply:You can kill yourself drinking too much water, Dc is about 5 times safer than AC.Try touching 9v AC to your tongue, totally different animal.

Reply:IMO the reasons for the smoother arc are:1 - DC generators produces at least three phases or more - and skewing the rotor laminations can help more = much voltage reduced ripple on the electrode.2 - The higher OCV helps maintain the arc when the electrode work gap widens3 - However the BIGGEE is the huge inductance of the rotor winding is always in the circuit, something that is not there with an alternator followed by rectifiers; the rectifiers act to cut off any inductance from the rotor/stator combination.  At best it is like having a pure DC battery bank.  You must add in a large external inductance else you will have no current stability.  e.g. You will often blow the end off the electrode when starting the arc.  The arc is difficult to maintain with small variations in arc gap because there is no compensating increase in voltage for a larger gap or decreased voltage for a smaller gap.  That's been my experience.Rick V 1 Airco Heliwelder 3A/DDR3 CTC 70/90 amp Stick/Tig Inverters in Parallel1 Lincoln MIG PAK 151 Oxy-Acet
Reply:Simple its a 40 volt dc welder
Reply:I don't know if they really inherently produce a better arc, but to me the design, simplicity, and CONTROL of the machine is what makes them awesome!compare to a trailblazer, xmt, maxstar, whatever. good a/c machines have an arc-control, dig, or whatever they wanna call it function. this is to try and give them the adjustability of a generator welding machine, with the adjustable volt-amp curve and what-not. but these machines do not have the range of selection, nor the ability to truly perform at the extreme ends of the spectrum like the s/a machines can. another key that I have noticed with the s/a machine is it just flat-out kills it with 6010 root and hot-passes. could be operator error, but my trailblazer is more difficult for me to put a good root in with. its either snuffing or blowing through. the s/a chugs right through everything, big gap, tight gap, doesn't care; just puts the metal in the groove. I think it has something to do with my high-amp/ low-volt settingsbosses stuff:trailblazer 325maxstar 200my stuff:sa 200fronius transpocket 180100 amp Lincoln w/f97 f350 DITKevin
