I bought my tig welder some months ago, but have only just got round to needing it.
I'm welding stainless tube thats about 2.5mm to 3mm thick.
I'm using a Lincoln Electric welder, about 80 amp's. A 2mm Tungsten that came with the welder, ground to a point.
I'l number my problem's so people can help me easier.
1) The first problem I have is my gas flow has to be really high or I melt the tungsten. (15cfm)
1.5) I need to have the tungsten as far as 10mm past the ceramic in order to get it to touch the piece (corners are really tricky).
2) The ceramic i'd guess has around a 10mm hole in it (not sure how to check the exact size?) I'm thinking i need to get a different ceramic in order to do the tricky weld's but don't know what will be best.
3) To butt weld the tube's i've found I don't need any filler rod, but need to buy a new regulator in order to back purge the weld's.
Many thanks for any help.
