Kevlar-stitched welding gloves: how to spec them right

Welding gloves take heat, sparks, spatter and abrasion — but the first thing to fail on a cheap pair is almost never the leather. It's the thread. Ordinary cotton or polyester thread melts and lets go at the seams, and the glove falls apart while the leather still looks fine. That's the whole reason a serious welding glove is Kevlar-stitched (or aramid-stitched): the thread survives the heat that would destroy a normal seam. If you're sourcing welding gloves, this is the detail to get right first.

Why the stitching thread matters most

Kevlar and aramid threads don't melt at the temperatures that break down cotton or polyester. In a welding glove, that means the seams hold when the glove is exposed to heat and sparks — so the glove lasts its full working life instead of splitting at the fingertips or thumb crotch after a few weeks. When a factory quotes you a "welding glove," always confirm the thread. Kevlar-stitched should be the default, not an upgrade.

Which leather for which job

The leather sets the balance between protection, dexterity and cost. The common choices:

Many buyers run a range: buffalo or cow-split gauntlets for stick and MIG work, goatskin for TIG. See the full welding glove range for how these map to specific styles.

The standards to hold a factory to

For the European market, three standards matter for welding gloves:

• EN 388 — mechanical risks (abrasion, cut, tear, puncture).
• EN 407 — thermal risks (burning behaviour, contact and radiant heat, small and large molten-metal splashes).
• EN 12477 — welders' gloves specifically, split into Type A (higher protection, less dexterity) and Type B (higher dexterity, for precision work like TIG).

Ask for the certificate and the tested rating, not just the logo. If a factory can't tell you the Type A/B split or the EN 407 numbers, that's a flag. For a deeper primer on the mechanical side, see our guide on EN 388 vs ANSI cut levels.

Cuff length and lining

Cuff length is a real spec decision, not a detail. Options run from a short 10 cm knit or stiff cuff for touch-up work up to a 36 cm gauntlet that protects the forearm for overhead and heavy welding. Linings — foam, fleece, cotton jersey — add comfort and some extra heat buffering, at a small cost to dexterity. Decide based on the actual work: overhead pipe welding needs a long gauntlet; a fabrication bench may want a shorter, more dexterous cuff.

What to spec when you order

• Leather type (buffalo / cow split / goatskin / sheep grain) and weight.
• Thread — confirm Kevlar or aramid.
• Standards required (EN 388, EN 407, EN 12477 Type A or B).
• Cuff length (10 cm up to 36 cm) and cuff style.
• Lining (unlined, foam, fleece, cotton jersey).
• Size range, color, and any logo or cuff branding.

Where SAS Agencies fits

Welding gloves are our flagship line. We make buffalo, cow-split, goatskin and sheep-grain welders in Faisalabad, Pakistan, every seam sewn with Kevlar or aramid thread, in cuff lengths up to 36 cm and with EN 388, EN 407 and EN 12477 options across the range. OEM and private-label only, MOQ from 400 pairs, first sample in 2–3 weeks. Send your spec and we'll match the leather, thread and standard to the job.

Frequently asked questions

Why are welding gloves stitched with Kevlar thread?

Kevlar (aramid) thread doesn't melt or burn at welding temperatures, so the seams survive spatter and heat that would melt ordinary polyester thread and split the glove open at the seam.

Which leather is best for welding gloves?

Buffalo and cow split for heavy MIG and stick welding and high heat; goatskin for TIG where dexterity matters; sheep grain for lighter, more precise work.

What standards should welding gloves meet?

EN 12477 (welding gloves, Type A or Type B), EN 407 (heat and flame) and EN 388 (mechanical). Always ask for the test report for the specific glove, not a generic certificate.
