I am fairly accomplished in normal TIG welding, but I have having a hard time learning cup- walking. Thanks!

In my experience, it was kind of a put down, as you set your electrode length, then just put the cup in the vee of a pipe joint, making it easier to keep a stable distance and obtain a better weld by just moving the cup along the vee. It is not usable in situations where you don't want the cup to contact the work. If you can TIG good, walking the cup should be child's play.

Thanks for the reply! For me it has been the opposite. I am quite good at freehand TIG. I have passed cert tests on pipe and tube using the the freehand technique (one on stainless pipe, the other on chrome-moly tube, both in the 6-G position). I find normal TIG to be the easiest welding process, but I have been trying to walk the cup for a LONG time, and have been getting frustrated by my lack of progress. There must be something I am doing wrong.

There must be something I am doing wrong. Try to get someone to show you. Maybe a teacher at a community college, or go to a steel manufacture yard, and talk to some people. Surprising some times what you can learn in a half an hour and a couple of cold ones. I have had several times I was ready to hook myself up to the machine in frustration, only to have someone show me in five minutes what I had been fighting for hours. One inch thick plate vertical travel up weave 7018 comes to mind...............

When you get the hang of that then switch to a smaller diameter cylinder till you are down to the size of a tig cup. It is a peculiar motion that takes practice. No use wasting tig consumables till you get that motion down pat. Then try fillet welds next.....then pipe.. Some guys will use a finger stall instead, a spare ceramic cup stuck on one of your fingers to act as an anchor point and then you won't have to touch the torch cup to the work. It's good to know both techniques. phil kangas -- The right of the people to keep and bear arms shall not be infringed.
