Thanks for the help appreciated but Yes that is what is so frustrating I hold his hands, talk, explain and still nothing. His individual beads by them selves look great, straight, consistent, good travel speed, so he sees the puddle just nothing around the puddle. cant reference where he is on the plate in relation to other beads edges of plate. even when he comes to the end of the plate he keeps going onto the table.
I taught PT at a CC and have had a few students with similar issues but usually trying one of the listed things to change works. Sometimes all you can do is just keep having them burn up a bunch of metal. I'm guessing he has watched you. Sometimes having an advanced student work with him a little helps, not to say your not doing it right. Even though you are telling him what to do, sometimes they students say they are doing what you tell them to but really don't or they don't realize it. My guess he isn't using his perrpherial vision and is to focused on the arc. Sometime students including myself just need to get really close, especially with GTAW. If the guy can see good then its just a matter of time before he just "gets it" and then a huge light comes on and he is super upset and super excited that it all comes together and wishes it would have happened earlier.
Has he taken a color acuity test? He just might not be seeing that particular color bandwidth.
Hi lwtfnd,
I have had students to do the same thing. I coach the students to have short arc lengths, but in this case I have them hold a longer arc to lighten the area outside of the puddle...for a while. I also have these students mark guide lines with soap stone.
