If you weld like the rest of us (OK, like I weld, I'll be give everyone else 
the benefit of doubt), you will never approach a 10% duty cycle at full 
power    :)     as you burn holes thru things, make boo-boos, etc.

So, probably either one will be fine.

Hi all,

Any opinions would be greatly appreciated, as I haven't done any welding
in alot of years and am just getting back into it.

Thank You...... DON

At the risk of a flame war I might suggest the miller *could be* rated in
"Sears" duty and the Lincoln is not. I have a Lincoln 100 MIG and I have
never had it pop the overload.
