A few tips for setting up for light ss tube:

Use a 1.0-1.5mm thoriated tungsten (red coloured band)

Use a nice fine grinding wheel on a bench grinder if available and grind the tip of the tungsten to a nice sharp point with shallow taper. The shallower it is the more focused the arc is.

Have the tungsten straight on the wheel when you sharpen, not at 90 degrees, so the grain runs down the length of the electrode.

Use the smallest gas cup you got, you'll be able to see better then.

You can allow the electrode to protrude past the cup by 2-3mm to help your vision even more but if you find you keep touching down with the electrode then you can push it back in to prevent it. Or have another whiskey to get rid of the shakes

Gas flow should be about 10-13 litres per minute but indoors you could get away with half that.

A good method for first-timers is autogenous welding, i.e. without any filler rod. Outside corner joints lend themselves to this. You can use 2 hands on the torch and with no filler to worry about all you need to concentrate on is fusing the 2 parent metals together. You'll be doing stunning looking welds in no time but they're not structural so beware.

I could go on but I'll save it for another time, best of luck

I've been doing all types of general fabrication in jersey since I left school 22 years ago.

Trying to escape from it at the mo!

It may sound far too easy! But have you considered a evening class just to give you a clue

To be honest it's not too bad.

Pic 1, Stainless Tea Strainer project - learning how high to set the amps etc

Pic 2, Stainless Steel practice welds

Pic 3, Joining two pieces of 3mm Mild Steel

These are my first welds ever so go easy on me

Mr and Mrs Nos came over last night to give me some tips and I have taken Nos's advice and bought some mild steel to practice on as stainless is too expensive to waste

The local course is 300 and doesn't really cover tig.

Well done mate...and fair play for posting the pics.

If no one has mentioned it to you yet, clenliness is near godliness when it comes to SS and Ally tigging....make sure your plate is nice and clean and get yourself a SS wire brush also....dont be tempted to clean your welds with a mild steel welding brush as you will contaminate the welds.
