Mike, looks like it's set up for a spoolmate 100 -
Miller Multimatic 200 Auto-Set Elite Welder 907518
If you want all your eggs in one basket, that looks like a good setup - at 29 pounds (40 with a full spool of wire) it's gonna be a lot more portable than the 211 I just sold, so if it's limited to a 10 foot gun like the 211, you would at least have the option of moving the welder much easier than the approx. 90 pounds (with full spool) 211.
I liked the 211 with same spool gun OK, but some of my projects are a bit big for a 10 foot gun (longest miller recommends), unless I wanted to hang the welder from a jib crane overhead -
So when I found a deal on a 252 with double running gear, 15 foot gun, 30A spool gun (never used) and 2 full tanks and 30 pounds of wire left on the
ONLY spool of wire the machine had ever seen, I bought it ($2500) and sold the 211 with spoolmate 100 to a friend whose needs are better matched to a smaller machine.
That was about 2 months ago, I've so far finished off that 30 pounds of wire and a 200 CF tank of C25 gas, and couldn't be happier with the 252.
If I were starting from scratch and didn't mind total downtime if
ANYTHING went wrong with a multipurpose machine, that 200 looks like a good choice... Steve
