A) standard work gloves for handling, but if finger dexterity is required, a pair of mechanics gloves fit the job nicely!
B) thin leather welding gloves
C) see B, or the thicker leather "cookie monster" (don't ask...) welding gloves
D) disposable, chinsy, "the cheapest that money can buy" gloves, although the second option within option "A" will also work.
Gloves are a funny thing, ya go cheap, it bites you in the rear. Ya go expensive, it bites you in the rear. The stitching usually fails first or guys go "hmm, nice gloves" and they grab em and use em for an application they weren't made for, and they get destroyed and they wonder "Hmm, glove broke. NEEYUHHHH! NEED NEW!" kaizanned in two hours...or 2 minutes if they're horny enough ("So SOFT!")
Now I'm not a business owner, but I've seen some strange things in my days....
