Like you know the diameter of a wheel can increase as the speed goes up, due to the centrifugal force.
Does anyone have data about this phenomena?
I'm specially interested in motorbike tyres. Thank you.
Yes, the tube is thin wall and I use a low amperage.
You are right, I didn't realize that the problem was that the helmet didn't recognize the arc (probably because the bad access, because in normal weldings it works ok).
Thank you very much rd400guy, your anwer has been a big help! :-)
I'm TIG welding a steel trellis structure. When I weld in areas with good access I have no problem, but SOMETIMES, when I'm welding an inner joint with not very good access, the light from the tungsten electrode is much more intense than normal till the point that I must stop because I feel that...
