When were 330 a/bp's made?

[H80N]

I just got another 330 yesterday. I have 2 others allready and only use the one cause it just keeps on trucking. Never any issue and welds everything. Iv had the one i use for 20 years and use it almost everyday.the second was for back up but have not needed it. The new one is in really nice shape and came with 3 torches,rad,pedal,etc. Just thinking though ,when were they made?

The 330 A/BP had a long run...

from what I am seeing...on the serial number spread... (HD684XX - JJ396XX)

it was built from 1973 through 1988....

I have an airco 3a, which is pretty much the same machine I understand. Mine was made in 1974 and still choochin along, although I haven't had it very long. You should be able to plug the serial number into the miller website and get the correct manual which will have a date range.
