Hi Guys.
I at last fired up my tig yesterday afternoon and manages to get about an hour and a half's practice before I'm ruined all my tungstens lol.
The set is a Chinese WSME - 200 which seems ok to me. I would say that the HF start can be a bit hit and miss.
Apart from that, I was using 2.6mm tungstens and 2.6mm filler.
Gas at around 7lpm on a proper bullet flow gauge.
Here are my results.
Just running a bead with no filler is not a problem, I can get consistent width and the shape of weld.
Adding filler seems to open up all sorts of problems but mainly from a contamination point of view. It always seemed to start almost spattering and I would get soot around the weld from where I had started using filler.
I wiped the rods down with Acetone and the were nice and bright and not oxidised that I could see.
I think the tungstens I'm using are too small for the size of material I have. Which will be what I am trying to weld. I'm off to BOC shortly to get some larger ones and some more filler rods.
I managed to get some welds I was happy with but I was'nt totally happy with the technique I used to get them if you see what I mean.
The lay wire technique seemed to work best for me but on fillet welds, I was using the torch like a heat gun. It may have been that the tungsten had melted away so I wasn't getting a decent arc.
Can you see anything obviously wrong before I go and waste more Argon??
