Hi Mark,

Although Lincoln has built some good machines the only one I ever used that was the best portable was the Lincoln Pipeliner as the arc stability is fantastic and I've never used another portable that was any better.
Miller answered Lincoln with the Miller Big Blue a portable and it was a good machine but the Pipeliner had a more stable arc. None of the smaller older(10yrs ago and older) portable machines could hold a candle to either the Pipeliner or the Big Blue. Don't get me wrong as other Lincoln & Miller portables were good machines but just not the best in arc stability.
Hobart's portable answer to Lincoln and Miller was a complete flop just like all there machines have been.

Now as far as wire machines go, Miller is tops as I never found anything better. Lincoln tried to catch up but failed. The only wire machine that could hold a candle to Miller was the Linde but over the years I've only used two Linde machines as there cost was twice of any of Miller's so Linde shot themselfs in the foot. Linde also had another draw back and that was any type of in-plant movement was not possible as they weighed a ton that even a good pallet jack had problems moving.

Indoor arc machines again I liked the Miller with Linde and P&H only being able to top the Miller but both the Linde and P&H were a "use in-place" machine as both were extreamly heavy. I believe where Linde and P&H made a name for themselfs was in automatic welding and when they were no longer suitable for automatic arc stablility then they'd get handed down to us manual guys. I know that was the way it was at Coors when I worked in there tank shop where we used them for SAW(Submurged Arc Welding).

The only machines that I would refuse to use was the Hobart as it was just a waste of time. I would spend more time repairing them than welding and then the arc stability was so bad.

I have not had chance to use any of the new machines of the past 10yrs or so thats why I don't answer "what machine type to buy posts".

Back in the late 80's and early 90's, Miller Lincoln was both having a problems keeping in the "black" and cut there quality down alot mostly changing to a aluminum tranformer winding that caused wild arc stability problems. I really don't know what either are using for transformers today.
