Hi all
Well finely fired up my welder [ R-Tech 160 ] in TIG mode , wow am I impressed about 5 minutes of current tweaking and I could mimic the stuff we had been doing at college.[ yes to the same poor standard ! ]
Using 2.4mm Tungsten and around 85 - 95 amps
So pictures 3mm-corner-outside and 3mm-corner-inside [ m/s ] show the results , these are as good as anything I have done at college , maybe a little flat and maybe a shade to much penetration ?
Then using the 2.4mm Tungsten and less than 45 amps
I tried some 40mm x 1.5mm m/s square box tube see pictures 40mm-1.5mm-box-side-2 , 40mm-1.5mm-box-inside got a joint and penetration looks fair , I may cut this open to see inside.
I think I should have used a smaller Tungsten and more current it was hard to strike an arc and the arc was feeble.
So helpful suggestions ?
I cannot yet feed the filler wire [ to much going on ! ] so I have to stop on the ling runs and reposition the filler.
Does anyone have good ideas how to safely cradle the torch between welds , can I make something to do this ?
Is there a rule of thumb for TIG ?
Say x,xmm tungsten for zmm thick plate using y amps ?
regards Paul
