For welding, all five Delta Plus leather welding gloves here are stated to EN 12477 Type A, the welders' glove class with more protection and less finger dexterity, as opposed to Type B gloves, which give more dexterity for fine work such as TIG welding. Then choose the length and build: TERK400 and TER250 are 40 cm with a 20 cm cuff, while TC716 and CA615K are 35 cm. TERK400 adds an aluminised Kevlar Preox back and scores level 4 for radiant heat, and TER250 uses THT treated leather that the maker describes as self extinguishing.
For handling hot objects, read the six EN 407 digits in order: burning behaviour, contact heat, convective heat, radiant heat, small splashes of molten metal and large splashes of molten metal, each from 1 to 4, with X meaning not tested. TERK500 XTREM HEAT reaches level 4 for contact heat, and the maker states protection up to 250°C for 1 minute and up to 500°C for 30 seconds. KPG10 is a knitted Kevlar and cotton glove with contact heat level 2, chosen when finger feel matters more.
For cold work, THRYM VV736 has an acrylic inner lining and a double latex coating. Its EN 511 code reads convective cold, contact cold and water penetration, and the maker rates it for cold environments down to -30°C.
