Tillmans are good, and there are knockoffs these days as well that are cheaper- because a good pair of Tillmans can run you fifteen to twenty bucks, if you go for the ones with kevlar thread.
The problem is- if you are working with small stuff, and lower temps, you need very thin gloves.
But the thin gloves wear out faster, and if your fingers are too close to the weld, which, sometimes, they have to be, your gloves get baked- and they get stiff and crunchy.
So the best gloves tend to have the shortest lifespan.
I buy the really thin tillmans, but only use them when its really the right glove for the jobs, and, most of the time, use a cheaper heavier cowhide glove.
Depends on the project, how good the weld has to be, and how much of a hurry you are in.
Gloves are a consumable.
I have a pile of used gloves about 4' tall and 3' x 3' I have been saving for a while to make some kind of art out of.
hundreds of pairs- we have been in this shop for 20 years, and there are sometimes 3 of us.
We usually wear out a pair of leather drivers gloves per person per month, and then a scattering of other special purpose gloves as well.
Holes happen. Stitching vaporizes, and fingers of gloves open up like file folders. leather gets so stiff from high heat that fingers wont bend at all.
