Welder MIG to TIG

I have a modern Mig welder which came with a stick option both with a standard euro connection to the machine which is also selectable + or _ Ground/torch.

Do any of you know if I can plug a TIG torch with standard euro connection into this, and where to buy a sensibly priced one?

It won't start I'm afraid. TIGs require a high frequency at high voltage to initiate and their plasma-ion'flame' IIRC. MIGs don't have that facility.

sale which I assumed is what I would get by attaching a TIG torch to my MIG.

Thin mild steel.

if you have a switchable + - earth probably will work but scratch start is horrible to use torch

They don't require HF start - although its a nice to have. Without it you have what they call "scratch start", where you strike the ark by lightly dragging the tungsten across the either the work (or better) a bit of scrap "lead in" stock.

Yup you can, although you will need a TIG torch with built in valve to allow control of gas. Also you won't get any luxuries like foot pedal control of the current. You will also need to scratch start since you won't have HF start, and lastly no AC so you won't be able to TIG ali. You may also find sustaining a good arc is harder since some mig machines may have a lower open circuit voltage than would be ideal for TIG work.

ISTR this old tony did a demo of running TIG on a (very cheap) stick welding inverter.

Yup, see here:

Why not just use the MIG, then?

Now that was useful.

Also need to lead out of the work unless the gas valve has a dwell after you break the arc.

Scratch start (jump to about 15 minutes for the TIG part)

Yes I was going to suggest a stick inverter, like the one I picked up from Lidl for IIRC around £70.
