Welding Tips and Tricks

How old would any one guess this to be? It's up for auction in Utah. There's no brand name on it as far as I know. The only description says it's an arc welder.

It looks very similar to the old Lincwelder.

it's a 600amp sa bullet type ac/dc generator made by lincoln. the instruction manual for this machine is # 1m-103-a. it had self indicating continuous controls and was popular in shipyards in the 1950's. there's still some in the larger shops today. i have used both the bullet and the linc-welder in the past and found the dual controls very hard to adjust.

I've also seen that bullet in my welding travels but can't remember for the life of me where. It may have been when I was shopping for a used machine for myself some years back. I don't feel so bad about my A/BP now

I have owned my machine for 17 years by now and it still cranks out sweet welds without any mystery from one day to the next.

We had bullets like that all over the shipyard. Ours were a bit bigger though 1200 -1500 amps each.
