Welder Problems Lincoln 225 Precision TIG
Posted: Mon Nov 17, 2014 10:56 pm
Hey,
So a few months back I bought a Lincoln 225 Precision TIG to practice for my level three training which is coming up soon. I've been working on open roots a ton in all positions just to keep up my skill level. I've been struggling way more than I expected especially with the amount of time i've been practicing. Im getting issues with blow back, the key hole is opening up fast and I've tried all the typical things: changing the amps down,(I'm already at 69 which is kinda low seeing I'm using 6010 3/32 rods i was at 76amps in the college if i turn it down anymore I'm sticking) trying out a new land and gap, focussing on my rod angle like angling it more into the puddle to help cool it down as well as preparation of the land and gap, I've been pushing the rod in their hard, I've tried the stepping method, and going up on my bevels to cool the weld down like jody showed in one of his open root videos. I've been going for weeks now and I can't seem to figure this out. If anyone has any input that would help a lot I feel I've tried all i can possibly think. Im wondering if its the machine itself, maybe it can't handle the precision I need to work on open roots. Need some help from all you welders!
