Thanks for everyone's advice! So, I finally connected the pedal and WOW, it's so much easier welding with it on 2T setting. Here is some aluminum intercooler pipe (~2mm thick) I just did with 90 amps. I start the pedal on full, then back off to about 75-50% and it works sooo much easier than using that switch on the torch.

I still need more practice to get my wrist in shape to keep the same distance from work piece consistent around pipe, but I'm getting there!
