I noticed in the video "tig welding 4130 chromoly tubing" there is a section talking about the pulse setting. Do you use pulse all the time or only when you in counter gaped areas? I use the eastwood tig 200 which doesn't have the pulse setting, I've made 2 bike frames with it so far and it seems to work great with thin tubing. I'm trying to create a better looking weld and wondering if you can make a nice looking bead without pulse.

Of course, you can make a nice-looking without pulse. Pulse just makes it easier.
The pulse feature is an automatic way of doing what you do with a manual remote, like a foot pedal. With pulse doing the work, you can focus solely on "move the cup, feed the rod", resulting (with practice) in a very uniform bead.
With just a foot pedal or thumb remote, it's a three-step process varying the amps manually, and it's challenging to consistently repeat your amperages with a manual control.

I have another question for the other fellow tig welders, I'm welding bicycle 4130 chromoly tubing (.035-.049) using er70s-2 .045 rod. eastwood tig 200 welder no pulse is set at 50 amps. w/ foot pedal. torch it a 9 with gas lens, tungsten 3/32 2% thoriated. My welds look pretty good but I'm getting too much burn through. How do I control the burn through?
