2011 Big Blue 400D

[jaker2480]

Hi everyone, this is my first time posting to this forum. I just recently picked up a Big Blue 400D without CC/CV and i was wondering a few things about it. I was trying to search the web for parts for my machine but besides random listings of parts on ebay i can not find a dedicated parts distributor online maybe im just not looking in the right place. I bought this machine because i want to go out onto the pipeline in the near future so im starting to buy tools and i seen this machine for a good price and pulled the trigger on it. I would really like to get a new faceplate for it and gauges because all the paint is wore off the front and the guages are unreadable except the hour meter that has fuel level integrated into it. My biggest issue is if i break down on the road this thing looks like it is going to be a pain to find parts for.

Has anyone ran these machines? i cant find very much info from other peoples experience with them so i figured i would ask.
Any information you guys have about these machines would be greatly appreciated.

I’m not familiar with that particular machine but don’t feel like the Lone Ranger, all those Miller engine drives had faceplates written in disappearing ink. There are replacements available on the internet. It’s a shame that they are like that as they are good machines

I’ve ran the big blue 400D a lot. All large structural jobs. The 400D (Deutz air cooled engine) was and still is a very solid machine.
I’ve ran lots of 3/16 7018 and .045 dual shield wire with the 400D. It welded very nice. I’ve also done a fair bit of carbon arc air gouging with the 400D. You couldn’t hurt these machines. The ones we used had the winter kit on them. In cold very weather conditions the oil pan heater is a must. The 400P (Perkins liquid cooled engine) was a better cold weather starter than the 400D. They were both excellent performing welders though.

Even though the painted verbiage is worn off you should still be able to make out the stamped SN on the face plate if it doesn't have a separate SN/Mod# tag on it. SN for a 2011 model year starts with MB followed by 6 numbers.

miller4less.com https://www.miller4less.com/ and millerserviceparts.com https://www.millerserviceparts.com/ are a couple of the best places to find genuine Miller parts.

If you don't have it already, you can download the Owner's Manual for the unit based on its SN here:

I just found out that it is not a 2011 model. Lj380053e is the serial number. Thanks guys for the links. Im working hard trying to buy equipment to get out on a pipeline and this was my first investment other than the truck.

Looks like a 2008 year model.

I have a BB400D bought new in 2003, with 7600 hours on it. Carbon arc gouge 3/8 rods all day in Florida! NR332 .068 or 3/16"7018. no problems, great on fuel. Never had it over heat. Replaced a few parts, Miller Tech always walked me thru it over the phone. Pipe welding, well its a brute, but a good hand can do it.
