I came across a decent looking Miller Maxstar 140 at auction. I know
the 150s and 200s surpass it in features and controls which would make
a good used 150 more desirable (and therefore more valuable/expensive).
So I searched this group and found that later model 140s apparently
gained thumb wheel control of current on the torch and if I read the
comments correctly one of the identifiers is whether or not the machine
has a 6 pin connector.
Looking at the pics of the 140 at auction, it appears that the torch
has a thumbwheel on it. Is that for current control? Or something
else? I haven't learned to TIG yet, bu tam looking at this machine as
a possible cheap way to get into it. But given the usefulness of
having current control at hand, I need to decide how much this older
machine is worth to me compared to waiting for a 150 or some other
machine with more features. So identifying the use of the thumbwheel
on the torch is helpful in this regard. I thought I'd ask the group
while I wait for a reply from the seller who may or may not know. TIA.
