Use the Weldas Deerskin for Tig, last ones I got for £6 a set, I say a set because they were all left hands I didn't mind as that is the one that always gets destroyed so I have loads of right hand ones spare Normally I pay £6.50 plus VAT I think.
For bigger Alu Tig jobs and smaller Alu Mig jobs I use Weldas SoftTouch 10-1050 and for bigger Alu Mig jobs I use the SoftTouch on the right hand and on the left I use thicker ones with a silver back. Not sure the make as I got them as freebies.
Another vote for Tegera. Somebody on here recommeded smaller gloves that were used by their wife I think. Really nice fit so plenty of dexterity. Small handed so no longer feels like I have potato sacks on my fingers. Only £9 delivered.
