Complete newbie, TIG-wise. Everything I've seen suggests that a 60 deg included angle is the most typical, penetration etc changing when you alter this. Does anyone have experience with this type of grinding fixture? (Amazon, Princess Auto, other places carry these.) I see that they only go to 22.5 deg., which presumably means 45 deg included angle. Or maybe everyone just eyeballs it on their bench grinder? Or maybe the angles available on this thing are just fine and it doesn't make all that much difference? TIA
