187 may have a purge/wire feed off setting and I just don't know where it is or how to use it. That is very possible.
I welded quite a bit with it this weekend. Thin 1x1 tubing for a driveway gate. It would weld as long as I could stand it. I would have to pull my hood off and take a break, welder was ready to go. I like it pretty good, very easy to use and you can get a lot of work done fast.
