matto Posted July 14, 2016 Share Posted July 14, 2016 Ended up in my truck. Guys dad bought it used in 1958 then used it for the next 50 years. Was made by Miller for Airco Quote Link to comment Share on other sites More sharing options...
jmccustomknives Posted July 14, 2016 Share Posted July 14, 2016 That is an oldy. They don't make 'em like that any more. Quote Link to comment Share on other sites More sharing options...
DSW Posted July 14, 2016 Share Posted July 14, 2016 Looks like it may be an early Miller AC only Dialarc. Those machines are tanks. I know a lot of guys who swear by old Airco's and their Miller cousins. I often see the Airco's go for next to nothing on CL compared to the Millers. I know a couple of guys who have the Airco versions of the Miller 320/330 AB/P's that they bought for less than $300. Not bad for a 400+ amp AC/Dc tig.

matto Posted July 14, 2016 Author Share Posted July 14, 2016 Replaced power cord and fires up great. All resurch I have done on it states that pre 1963 where all made by Miller. I will get it all cleaned up and replace worn parts. Miller still list and has parts for them. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted July 14, 2016 Share Posted July 14, 2016 Generally the older stuff is way overbuilt, copper wound, etc---but you might check up on what tends to go bad and stock up ahead of time as inventories of repair parts can disappear with the stroke of a bean counter's mouse these days... I have an old Lincoln Tombstone that may very well be older than I am and I expect the grandkids will be fighting over it...reminds me that it's time to take the cover off, blow out the dust and check everything...

Michael Posted July 14, 2016 Share Posted July 14, 2016 I've got an old Miller Thunderbolt I picked up for $50......10 years ago now. Built like a tank. Quote Link to comment Share on other sites More sharing options...
ggraham Posted July 14, 2016 Share Posted July 14, 2016 I bought a lincoln ideal arc 250 about 20 years ago for less than scrap, some knowledgeable person had condemned as shorted but all that was wrong was the cooling fan had a dirt dauber nest stopping the fan. cleaned up, checked it out, worked great, 100% duty cycle up to 140 amps.

DSW Posted July 14, 2016 Share Posted July 14, 2016 Nice. It's one of the AC/Dc ones as well. Those machines probably have one of the nicest arcs outside the old electric generator welders. Quote Link to comment Share on other sites More sharing options...
matto Posted July 15, 2016 Author Share Posted July 15, 2016 Thomas I have a manuel coming from Miller and will start taking it apart and cleaning it up this weekend. Michael I have my grandpas old thunder bolt. He got it in the late 60s or early 70s. Fun little welder. Quote Link to comment Share on other sites More sharing options...
jmccustomknives Posted July 15, 2016 Share Posted July 15, 2016 You can go to millers website under support and look up a miller machine and download the manual and parts books for them. Lincoln has the same set up. Quote Link to comment Share on other sites More sharing options...
