A neighbor expressed an interest in welding, so we spent about an hour today showing him how to strike an arc and run a bead. I started him on 3/32" E7014, but I thought the larger, more visible puddle of a 1/8" rod might be a little easier for him to see, so we moved up to some 1/8" E6011 and 7018. Before too long, he was laying down beads pretty decent. Even that first hour made a big difference between sticking the rod a bunch and him just firing right up. We ended up doing several overlapping passes on a butt joint and a fillet joint for a closer.
We got the 7014 dialed in at just the right heat level so the slag was popping off on its own in one piece! Nice to know that, with this digital welder, I can just turn the dial back to that number if I need to. With my old welder, I would have been afraid to touch the output lever because I'd know I'd never get it back just right in that spot.
All told, we burned maybe a pound of rod, so I'd say the little 160 STH has been put through its paces. The arc force control made it much easier to teach him to maintain arc gap, since it was relatively safe to have him drive the rod into the puddle without having to worry about extinguishing the arc. I'm still getting a feel for how this welder runs a little differently than my old one, but it's coming together. The 7018 we ran was just beautiful.
This weekend, I'll be going to an informal welding workshop, where I plan to hook the 160 STH up to a borrowed argon tank and try out the TIG features. I'm going to swing by my LWS and pick up some tungsten and some filler rods some time this week.
