Last night was my first time ever trying to run some TIG beads. I have taken a basic welding course at local adult ed for stick/mig. Would appreciate any comments on the welds... Hope some day they look as nice as some I have seen on the site from others. For the most part I could keep the electrode out of the puddle, but when I went to feed the filler wire in it seemed to stick a little which caused me to be jerking it back to release.. I also noticed I got some build up on the back of the plate, so I'm guessing amperage was too high?I was running the beads on mild steel (.115)Here is my setup:Miller 200DX, HF Start, DCEN, 95amps, 15cf, 3/32 tungsten (red) ground to point, and 3/32 ER70S2 filler, prep'd with flap disk,and acetoneThanks,Last edited by David R; 11-22-2007 at 07:50 AM.Reason: Fix Pics
Reply:A little hot. Once you run a few beads on plate like that, the plate heats up and you need less heat.A good start, now do it again DavidReal world weldin. When I grow up I want to be a tig weldor.
Reply:Also looks like you were adding the filler to fast/to much. Try getting your puddle going counting to 1, then put the rod at the edge of the puddle. Then count too 2 and move and repeat. That should help a little ( very little since it's coming from me). But that should help you get a tempo going with the welding.
Reply:Yes I would say a bit on the hot side. But very good for some first tig beads.mm135HTP Invertig 201 With water cooler9" Southbend LatheLots of hand tools. |
