Default 1970 Miller Trailblazer 4J 10KW power plant/welder help

I have what I think is a 1970 date Miller Trailblazer 4J welder and power plant. I have a parts book and a operator manual but neither tell which MIG and TIG accessory units work with it.
This one also has the optional 115v AC generator to supply power foe lights and tools while in the weld setting. It is powered by a 4 cylinder Jeep engine. In power mode it is rated at 10KW 230v and 115V AC. There is also a 115V DC plug.
Any ideas on a MIG wire feed? Thanks, Tom

Did you go to "Miller Welds" web site? With the serial # you can download the Manuals. Miller site is Very Good for info on any equipment they make.

+1 on Keith's note- under Support/Documents, you can plug in the model and serial number range to download the exact manual... or... if you DON'T see it there, Email Miller's support staff, they'll pull a paper copy, scan it, and send it to you (then post it on their excellent library).

If your TrailBlazer WAS set up to work Constant Voltage (rather than Stick/Tig Constant Current), you'd be able to use any similar-vintage or newer spool gun (I believe they had just two types then) or any of the feeders. The 10A and 10E feeders were bulletproof workhorses... the later S52 brethren had a neat LED segmented display to identify wire speed, they used circular connectors, but take off the connector and hardwire like the 10-series, they'll work fine.
