Gee... My reputation precedes me!
I prefer the Trailblazers as well.
Main difference between the Bobcats/Rangers and Trailblazers is the Trailblazer is designed to give full AC output while welding and without messing around with the fine current adjust to get full output.
The lower end Rangers and the Bobcats all have one set of armature windings and two sets of field windings, one for weld out and one for AC out. Since there is only one set of arm winding the AC output is regulated by the same circuit as the weld output so you have to set the fine adjust at 10 for full ac out on these machines.
I have had a couple of these machines come in from the customer wonder why they were not getting full output of AC. They had the fine adjust knob set low! OOPS!
The trailblazers have essentially two alternators on the same shaft. Two sets of windings and two sets of field windings. This allows the machine to regulate AC output independent of weld output.
Also the TBs come with the options for remotes for wire feeding, tig, etc. They are a really sweet machine.
Also both millers now have the engine completely enclosed which makes it quieter and runs cooler. Cleaner too.
The lincolns are not that bad, but I still wouldnt but one.
