Manufacturer Reviews

They call me aka the moose

I started my welding bissness back when I was 19 started out with the Miller bob cat 225 then moved up to the Miller trailblazer 302 had it for all most 16 years and the motor spun a rod bearing. So know iam move up to a big blue 400 x pro looking forward to working with this machine for the next 20 years or till I retire once I take delivery of the unit and have it wrapped with my logo I will put it on the Miller website so everybody can see

Lorenzo

Used on a Structural Steel Erection Truck, Full Pen Welding all day long with 232 Flux Core .072 Wire. Starts every time without fail. Quite the machine for the size and very very quiet. Main reson for purchase is 1) it is a diesel drive and 2) I have never had any problems with Miller products and I have owned every major brand since 1972. Im still waiting to save a little money to purchase a wireless control wire feeder to be able to use all the features of the 400 Pro.

The weld guy

This machine was purchased to go on one of our field service truck. This unit has to preform many tasks from pipe welding, structural, tig, and mig. this machine fits the bill nicely. Great arc performance under all conditions XX10 to XXX18. Welders like the CV as well when used manually or with an automated system. All around great machine.
