Welding gloves look like a simple leather product and are anything but - the leather grade, the stitching thread, the lining, and the seam construction all decide whether the glove lasts a month or a shift. Here is a working guide to sourcing MIG, TIG and stick welding gloves, including the differences welders actually care about and the corners suppliers cut that you will only discover when a seam burns through.
MIG, TIG and Stick Are Three Different Gloves
The first mistake buyers make is ordering welding gloves as one product. The three main welding processes need genuinely different gloves. TIG welding is precision work at lower heat, so TIG gloves are thin and supple - usually goatskin - for maximum finger dexterity. MIG welding produces more heat and spatter, so MIG gloves are thicker cowhide or split leather with more insulation and a longer cuff. Stick (arc) welding is the hottest and dirtiest, demanding the heaviest split-leather gauntlets with the most heat protection and the least concern for dexterity. If your customer welds across processes they may need two SKUs, not one - and a supplier who offers one welding glove for everything does not understand the trade.
Leather Grade Decides Almost Everything
The single biggest driver of welding-glove quality and complaints is the leather. Side split leather (from the side of the hide) is the workhorse for MIG and stick gloves - heat-resistant, durable, and economical. Shoulder split is a step down, more uneven. Grain leather and goatskin give the suppleness TIG welders need. The corner cheap suppliers cut is leather thickness and consistency - they buy thinner, more variable split that runs hot spots and wears through at the palm. Specify the leather type and a minimum thickness (in mm) on your spec sheet, because welding leather is sold by thickness and that is exactly the number a cost-down supplier will quietly shave. See our broader glove materials guide for cowhide versus goatskin economics.
The Thread Is Where Cheap Gloves Burn Through
Here is the detail almost no buyer checks and every experienced welder knows: the stitching thread. A welding glove sewn with ordinary polyester or cotton thread will have the thread melt or burn at the seams long before the leather fails - the glove falls apart at the stitching while the leather looks fine. Genuine welding gloves are sewn with Kevlar (aramid) thread, which does not melt at welding temperatures. This is a small cost - cents per glove - and it is the most common corner cut because it is invisible in a photo and a showroom sample. Put Kevlar-thread sewn seams on your spec sheet explicitly and inspect for it; it is the cheapest spec line that prevents the most returns.
Lining, Cuff and Seam Construction
Beyond the leather and thread, three construction choices matter. Lining: a cotton or wool lining adds heat insulation and comfort - foam or fleece lining for cold-weather welding, unlined for hot-environment dexterity. Cuff: welding gauntlets run from a short 4-inch cuff for TIG up to a 14-18 inch gauntlet for overhead stick welding that protects the forearm from falling spatter - the cuff length is a real spec, not a default. Seam construction: welted seams (with a leather welt sewn into the seam) protect the thread from direct heat far better than a plain seam. These three together separate a glove that survives a season from one that is comfortable for a week.
Heat, Standards and Honest Claims
Welding gloves in the EU are typically certified to EN 388 (mechanical, including abrasion and tear) and EN 407 (thermal risks - contact heat, radiant heat, small splashes of molten metal). EN 407 uses a six-digit code for different thermal hazards; the contact-heat and molten-metal digits are the ones welders care about. Be wary of suppliers who claim high heat resistance without an EN 407 report, and remember that a leather glove protects against welding heat and spatter, not against sustained high-temperature contact like furnace work - that is a different product. We supply EN 388 and EN 407 reports and are clear about the boundary between welding protection and high-temperature handling.
MOQ, Pricing and Custom Options
Welding gloves run from 500 pairs MOQ for a stock pattern, 1,000 for fully custom, FOB Ningbo roughly USD 1.20 for a basic split-leather MIG glove up to USD 4.50 for a premium lined goatskin TIG glove with welted seams and Kevlar stitching. Customization is mostly about leather choice, cuff length, lining, and a branded cuff - logos go on the gauntlet, debossed or screen-printed, since embroidery on heavy leather is fussy and the back of a welding glove sees heat. For decoration trade-offs on leather specifically, our decoration guide covers why debossing suits leather better than embroidery here.
How to Vet a Welding-Glove Supplier
Ask three things and you will sort the real welding suppliers from the general leather-glove factories. First: what leather grade and thickness, and can you show the EN 388 and EN 407 reports? Second: are the seams sewn with Kevlar thread - and watch whether they immediately understand why you are asking. Third: what cuff lengths and lining options do you run as standard? A supplier who talks fluently about side split versus goatskin, Kevlar stitching, and welted seams makes welding gloves; one who treats it as just another leather glove will sell you a product that burns through at the seams. The full vetting checklist covers audits and payment terms.
Our Honest Position on Welding Gloves
We build MIG, TIG and stick welding gloves as separate products with the right leather grade and thickness for each process, sewn with Kevlar thread, with welted seams and the cuff length your customer's work demands, and certified to EN 388 and EN 407 with the reports to prove it. We will tell you honestly that a welding glove protects against welding heat and spatter, not sustained furnace contact, rather than overstate the heat rating to win an order. The thread and the leather thickness are the two specs we will not let a buyer skip, because they are exactly the corners that turn a cheap welding glove into a warranty problem and a safety risk.
