Default Use a welder to test a welder?

I hear old timers talk about using one pipeliner to start another and to test a generator of a non running pipeliner by hooking a running one to it. I assume they are doing this by connecting positive lugs to positive and negitive to negitive.Anyone know for sure?

They aren't testing one they are just using the other welder to excite the armature and turn the other one over to start it.

Back in the early 70s I had an old Lincoln portable that had a chronic starter problem. I also had an old 20s vintage GE dc machine. I would crank the GE all the way up to the stop and turn the Lincoln all the way down then clip a piece of scrap iron between the electrode holders. Pull out the choke and touck the ground clamps together.

This worked without fail many times. Although I don't know if I would try it on some of the modern solid state machines now days.

My question is: can this change the polarity if done wrong?

I've got an old SA200 pipeliner that can be stubborn to start in the winter if it has been sitting for awhile. In the shop I've got a Miller 300, and I've used the Miller 5 or 6 times to start the Lincoln with no problems. I just hooked the ground to ground and pos. to pos. I was a little nervous the first time, but after that it was old hat. The lincoln would turn over almost at running speed! I guess it is like using the welder as a starter/generator. I knew one guy that used 3 12 volt batteries connected in series to start an old lincoln with no starter.
