Have you tried contacting Tecarc who make the machine directly?Can anyone help? I have just acquired an Oxford Mig 170 but unfortunately it does not have a manual, it's a 1980's machine (the same as one described in a post on here). Any help or information would be much appreciated.
I have the Oxford 180-1 (it's only about 1-year-old). Having picked it up off the floor only yesterday to load it into my van, I can testify it is quite heavy.Cheers for the replies, it appears to work ok and looks to have been a good piece of quality kit in the day, Weighs a ton due to the transformers. I suppose I'll just have to experiment with it, trial and error!
I have a 1980s Oxford 120s and I had a MIG300 - all their duty cycles knock more recent stuff into a cocked hat. The 300 was rated for 225A at 100% - and it weighed almost as much as Cyril Smith.Cheers for the replies, it appears to work ok and looks to have been a good piece of quality kit in the day, Weighs a ton due to the transformers.

I purchased one a couple of years ago and the 'manual' is pretty useless really!Can anyone help?

Drop a message to @Tom Orrow L on this forum. He deals with Oxford all the time so I'm sure he can get the info you require if he doesn't know himself.Thanks for the replies; the main issue I have is with the earth return cable as there are three ports for this on the machine under the heading inductance - Max written on one, blank on the middle one and Min on the other .
Cheers
if in doubt set it in the middle and just have a play ,,,Thanks for the replies; the main issue I have is with the earth return cable as there are three ports for this on the machine under the heading inductance - Max written on one, blank on the middle one and Min on the other .

Sorry to be so tardy in replying, but your advice is really helpful. Many thanksRegarding inductance settings:
Having an inductor in the MIG welder output circuit helps with flow-out ( wetting ) of the weld pool. When the wire touches the workpiece there is a dead short. Since MIG welders use a constant-voltage power source, current rises very quickly. The inductor slows the rate of current rise, which also helps to protect the rectifier diodes. It alters the time ratio between the dead short, which melts the wire, and the arc, which heats the weld pool and the metal of the workpiece.
More explanation of inductance in MIG welding here:

https://www.weldingtipsandtricks.com/mig-welding-inductance.html
From the latter link, the basic advice is: use the low inductance setting ( "Min" ) for thin metal, and high inductance ( "Max" ) for thick metal.
Thanks for the advice and replying, much appreciated!I have the same machine. I haven't used it much till now as it's been a spare for my Britweld but that one is out of comission for the moment so have been using the Oxford. I'm mainly welding thinish stuff (bicycle frames and 1.6mm or 2mm box section) and have just used it on middle inductance setting which I find gives an easily controlled smooth weld with plenty of penetration.
It certainly is built like a tank and no way is it portable but it's a lovely old simple machine and well worth it's space in the workshop.
