A factory-level buying guide to welding gloves by process: TIG dexterity, MIG spatter resistance and stick-heat protection. See where split cowhide, para-aramid stitching and 35-45 cm cuffs actually matter, and where a generic all-purpose glove is just a compromise.
Choose the glove by welding process, not by one generic spec
TIG, MIG and stick do not load the same part of the glove, so a single style brief usually produces a compromise. TIG is the most dexterity-led job: the welder is working a torch head, filler rod and trigger control in short movements, so the glove needs a close pattern, low seam bulk and softer leather. In production terms, that often means goatskin or soft cowhide at about 0.8-1.0 mm, with a narrow palm, a slim finger box and minimal lining on the palm side. If the glove is built like a MIG glove, the hand loses too much feel and the operator starts fighting the tool instead of controlling it. MIG and stick need a different build. The main load is spatter, radiant heat and occasional contact with hot metal, so abrasion resistance and coverage matter more than fingertip precision. Split cowhide or shoulder split at about 1.2-1.4 mm is the usual base material, with a longer gauntlet cuff and reinforcement at the thumb saddle, forefinger and back of hand. For overhead MIG or heavier stick work, a 35-45 cm overall length is common because the cuff has to stop sparks from travelling straight into the wrist opening. Short cuffs can work only in lighter bench work, and usually only when the sleeve arrangement is controlled. A factory can make one glove that sits between these jobs, but it is still a compromise. The real complaint from the field is usually not a lab failure; it is a welder saying the glove feels wrong after one shift, either too stiff for torch work or too light for spatter-heavy welding.
Leather, seams and thread decide the real heat performance
The leather is the first barrier, but it is not the whole thermal system. Split cowhide is the workhorse for MIG and stick because it handles abrasion well and keeps material cost in a workable band for larger programmes. Grain cowhide gives a cleaner face and a better retail look, which matters for display packaging, but a smoother surface does not automatically mean better welding performance. Goatskin is the usual upgrade for TIG when the buyer wants softer hand feel, better grip and less break-in stiffness. It is easier to shape into a precise finger pattern, but it normally costs more and hide consistency is less predictable than a basic split order. Thread choice is where low quotes often hide the real weakness. Para-aramid sewing thread is the normal spec for better welding gloves because it tolerates sparks and short heat exposure better than polyester. Some buyers still ask for Kevlar thread by name, but in factory language the important point is the actual aramid content, thread count and stitch density. A strong thread with too few stitches per inch will still open early at the thumb crotch or index finger if the glove flexes hard all day. Seam placement matters as much as thread. If the thumb crotch seam sits in the direct line of spatter, it burns through first. Covered seams, welted seams and rolled finger joints can extend life, but they add bulk, labour and sewing time. That extra bulk is normal on a stick glove and often useful on a MIG glove, but it becomes a problem on a TIG glove where the hand has to stay close to the torch. For sourcing, the seam build is not a styling choice. It is a use-case decision that changes break-in, heat handling and unit price.
Cuff length, lining and pattern are where comfort is won or lost
Industrial welding gloves usually land in the 35-45 cm range when the job involves MIG or stick. That is not a fashion number. It is the length needed to reduce spark entry at the wrist, especially in overhead or out-of-position welding where molten droplets run down the back of the hand. A short cuff can work for lower exposure tasks, but only if the operator wears jacket sleeves correctly and the jobsite is disciplined. If the cuff is too wide, debris can fall inside. If it is too tight, the glove is hard to pull on and even harder to keep on during a shift. Lining should be chosen for the work, not added to make the spec sheet look heavier. Cotton jersey, fleece and full cotton lining improve initial comfort on split leather and help reduce the scratchy feel of new gloves. Over-lining makes the glove hotter and bulkier. For TIG, many buyers prefer an unlined palm or a lighter lining only on the back of the hand so the torch hand keeps sensitivity around the trigger and filler rod. For MIG and stick, a fuller cotton or fleece lining is easier to justify because those jobs already accept less dexterity in exchange for heat buffering. Pattern shape is another detail that is often missed in RFQs. A pre-curved finger pattern can improve grip and reduce seam stress, but it needs more accurate cutting and grading. Palm reinforcement and thumb saddle patches improve abrasion life against edges and grinder dust, but every extra layer changes break-in time and sewing cost. A fully reinforced gauntlet takes more labour than a basic driver-style leather glove, so it should not be priced like a standard workshop glove. Cutting, skiving, panel count and stitch time all move the cost, not just the leather grade.
EN 388 and EN 407 tell you more than marketing words do
Welding gloves are not only about heat. The hand still contacts sharp edges, tack welds and fabricated parts, so EN 388 is the mechanical standard a buyer should check first if the glove is sold into Europe. The code matters more than labels like heavy duty or professional grade. A glove may look thick in photos and still fail early if tear resistance is weak where the thumb joins the palm. When comparing suppliers, ask for the exact EN 388 result, not a vague statement that the glove is tested. For thermal exposure, EN 407 is the relevant standard, but it is not one simple heat number. Contact heat, convective heat and small splashes of molten metal are separate tests, and a glove can be decent in one while weak in another. That is why a TIG glove and a stick glove should not be judged against the same expectation. The TIG operator needs hand control and lower bulk. The stick welder needs a more protective build that accepts stiffness and a heavier cuff. If a buyer needs EN 388 or EN 407 references on the glove label or in the technical file, the production sample must match the tested sample in leather, thread, lining and pattern. A similar-looking glove from another line is not a valid substitute. For regulated markets, the exact code, test scope and sample reference should be settled before the PO, not after bulk sewing has started.
What a Yiwu glove factory can make, and what it usually will not
Our core work is cut-and-sewn leather gloves and mixed-material industrial gloves, so TIG, MIG and stick models are within normal OEM scope. That includes split cowhide gauntlets, goatskin TIG gloves, para-aramid stitched builds, cotton or fleece linings and palm or thumb reinforcement. It also includes common branding methods such as embossing, woven labels and hangtags. What we do not do is promise that every custom change is free. Once the buyer changes cuff shape, leather grade, logo position, trim colour or panel count, the cutting yield and sewing time change too, and that shows up in the price. A realistic MOQ for many welding glove programmes is 500-1000 pairs per style and colour. Lower quantities may be possible, but the unit price usually rises because leather nesting loss, setup time and sewing labour do not fall in the same proportion. For lead time, a repeat order can often move in about 30-45 days after sample approval. New builds with special cuffs, mixed leather constructions or unusual trims take longer because the first sample often needs one or more rounds of fit correction and material sourcing. That is normal factory flow, not a special service. We also do not push decorative features that weaken the glove for no benefit. A glove meant for a site trailer or welding bay does not need glossy packaging, colour blocking or retail tricks if those features consume budget that should go into leather, thread and cuff length.
Sampling, stitching and packing should be specified before PO
Sampling is where most welding glove mistakes show up, because the hand can feel what a spec sheet cannot. Buyers should check finger length, thumb mobility, cuff opening, seam lay-flat and whether the lining shifts after repeated flexing. For MIG spatter gloves, the sample should be made in the exact leather, thread and cuff length intended for bulk. A near-match is not good enough when the real issue is how hot metal lands on the back of the hand and whether the thumb saddle opens after repeated flex cycles. Ask the factory to mark reinforcement boundaries on the sample. A shift of even 10 mm in thumb saddle coverage can change both wear life and finger comfort. If the glove is intended to be worn over a jacket sleeve, the fit test should be done that way, not only on bare hands in a showroom. A glove that feels acceptable on a table can pinch, twist or trap heat once it is worn for a full shift and the hand starts sweating. Packing should be fixed before production. A common export pack is 12 pairs per polybag and 120 pairs per carton, but bulky welding gloves often change that count because 40 cm gauntlet cuffs take more carton volume than short work gloves. On a 20 ft container, volume usually becomes the limiter before weight. That matters on FOB Shanghai or FOB Ningbo because carton dimensions affect pallet count and loading efficiency. Inner polybag print, size breakdown and carton marks should be approved before bulk sewing starts, not after cartons are already sealed. Once packed, changes become waste and rework.
How to compare offers without buying the wrong glove
When three factories quote welding gloves, pair price alone tells you very little. Compare leather type, leather thickness, cuff length, lining, thread and whether the glove is built for TIG, MIG or stick. A lower quote often means thinner split leather, shorter cuffs, standard polyester thread or fewer reinforcement panels. That is not automatically wrong for light work, but it is usually a false economy in a spatter-heavy booth or a stick-welding line where the glove is hit repeatedly by heat and abrasion. The usable RFQ line is short and specific. For example: split cowhide MIG glove, 40 cm gauntlet, cotton-lined back, para-aramid thread, no touchscreen, OEM logo on cuff. That gives the factory enough information to price honestly and say where it can and cannot meet the brief. If the buyer wants a lighter TIG glove, say that plainly and accept the trade-off: less bulk, less heat buffer and usually a higher material cost per pair when goatskin is used instead of generic cow split. For procurement, the practical question is not which glove looks toughest in a photo. It is which glove matches the welding process, the wear environment and the margin target. The cheapest quote is rarely the cheapest glove once the weld bay starts using it. A glove that lasts longer, fits the task properly and is built around the right standard and seam construction is the one worth reordering.
