Choosing Welding Supplies

What a trade workshop should PUT ON ITS SHELF and keep buying — specifying, comparing and standardising welding consumables, abrasives, PPE and gas across a working shop. The territory is the PURCHASING DECISION, made by the person who owns the stock and the spend: - specifying the right consumable for the standing work of the shop, and writing that spec down so reorders stay consistent - comparing OEM against aftermarket tips, nozzles, liners and diffusers, and where the cheap option actually costs more - standardising consumables across multiple machines, benches or sites so one part number covers more stations - reading wire, rod and abrasive classifications well enough to order the right thing and catch a wrong substitution - pack sizes, spool sizes, shelf life, storage and rotation — what survives a Victorian workshop and what degrades - when a product change, substitution or discontinued line forces a re-spec - abrasives and PPE selection as consumable categories with their own wear, cost and compliance drivers Audience: Australian trade workshops, fabricators and industrial buyers — purchasing managers, workshop managers, store persons and owner-operators who hold the account and sign off the spend. Metric units, Australian gas and cylinder naming, Australian standards. OUT OF SCOPE — do not grow questions about any of this: HOW TO WELD, in any form. No technique, settings, machine setup or arc behaviour: no puddle, bead profile, travel speed, heat input, stickout, penetration, burn-through, distortion, preheat, polarity, transfer mode, gas flow tuning, or "why does my weld look like this". No weld troubleshooting or weld defect diagnosis. No DIY, hobby, home-garage, weekend-project or first-time-welder framing, and no farm-gate, trailer-repair or automotive-panel projects — WeldCo sells to trade, not to hobbyists. No US units or US market assumptions (no fractional-inch material, no 110/120V machines, no pound-rated cylinders, no "aluminum"). WeldCo supplies and services equipment and gas; it does NOT teach people to weld, and a question whose honest answer is a welding lesson belongs to no WeldCo cluster at all.
