Super stoked to finally ground my welding stand. I think on average, I waste a good 15 minutes clamping, unclamping and clamping the frame to the ground lead. That's just a guess, but it will be interesting to see what kind of time savings I'll gain. It will certainly allow me to keep a good flow going and not tangle up all the leads constantly. Things will be tidy, or as Poppy used to say "Just So".

Friction Stir Welding was invented by Wayne Thomas at TWI Ltd in 1991 and overcomes many of the problems associated with traditional joining techniques. Friction Stir Welding is a solid state process which produces welds of high quality in difficult to weld materials such as aluminium and is fast becoming the process of choice for manufacturing light weight transport structures such as boats, trains and aeroplanes.

Methuen Construction (a bit of a misnomer; they are two towns away in Plaistow NH) is a construction company. Some UMass Lowell students (I was one of them) took a tour of this company. This photo shows welding. I took three welding photos, but the other two aren't uploaded here because they have people in them.
Taking a different approach to independently adjustable EN and EP amperage. The common approach is running higher EN amps to put more heat into the part and less into the tungsten. I found I had to turn my balance down to get enough cleaning and that resulted in more tungsten degradation with a 3/32" tubgsten. I started experimenting with running the EP amperage higher than the EN amperage. Here, I'm running 45% higher amps on the EP side and turning up the balance to 80-85% EN. This has allowed me to run a smaller (1/16") tungsten with a fully pointed tip for much greater control. The point barely degrades after tacking and welding out two front triangles. I'm thrilled.
