Hello everybody. I was surfin away and found info on a new Big Blue 400 pro, it isnt listed in the drop down above its in the new releases section. Also seen listed a BB500 pro which is listed on the above drop down, but doesn't show in the 2014 full line catalog. What gives? Why do they have basically 4 machines in the 400 amp range. BB300pro, BB350 pipepro ,BB400pro. and BB400 Ecopro? Is one of these models on borrowed time? I understand having a specialty pipe machine with all the bell and whisltes, but seems like overlap with the 3 others. The 500pro looks like a nice unit , also wondering if the reg BB400 and 500 will be phased out. I have to say i like the single range dial with the digital meters as opposed to taps, Not really for me but for helpers that dont know how to properly adjust range and volt curve settings. Have to say i like the Vantages for this reason, but now Miller is doin it.
