Choosing the right welding consumables and equipment comes down to matching the product to your material, welding process and quality requirements — not simply buying the cheapest option. ER70S-6 is the all-round choice for mild steel MIG, 308L and 316L cover most stainless TIG work, and 6013 and 7018 handle the majority of MMA fabrication. The pages below break down every buying decision in detail, from filler wire and shielding gas to torches, PPE and fume extraction.
This hub is the starting point for our complete welding buying guides. Each guide answers a specific buying question with a direct, practical recommendation grounded in the products and standards professional fabricators rely on. If you would like a recommendation for your exact application, our technical team is always happy to help — talk to a Weldability SIF welding specialist.
How to approach any welding buying decision
Every sound purchasing decision starts with the same questions: what material are you welding, by which process, to what thickness, and against which mechanical or standards requirements? Once those are clear, the correct consumable usually follows. The lowest purchase price rarely delivers the lowest production cost — high-quality consumables reduce spatter, rework and downtime, which is where the real savings sit. For coded or critical work, always check the consumable meets the relevant BS EN ISO or AWS standards specified by the welding procedure.
Consider five things before you buy:
- Parent material and grade — mild steel, stainless (304 or 316), aluminium alloy, or dissimilar metals.
- Welding process — MIG, TIG, MMA, flux-cored or laser, each with its own consumable family.
- Material thickness — drives wire and electrode diameter, and often the process itself.
- Standards and mechanical properties — coded work may specify low-hydrogen or certified consumables.
- Service environment — corrosion resistance, marine exposure, food processing or outdoor use.
Buying by product
Filler wire and rods
MIG wire buying guide — ER70S-6 for mild steel, 308LSi and 316LSi for stainless, ER4043 and ER5356 for aluminium, plus how to choose diameter, copper-coated vs copper-free, and the right wire for thin, thick and structural steel.
TIG rods and tungsten buying guide — matching 308L, 316L and 309L filler to the parent material, choosing ER70S-2 for mild steel, and selecting tungsten electrodes for AC and DC work.
MMA electrode buying guide — when to choose 6013 vs 7018, how to size electrode diameter, and which electrodes every workshop should stock.
Flux-cored wire buying guide — gas-shielded vs self-shielded, when to choose flux-cored over solid wire, and the best wire for structural and outdoor welding.
Gas, torches and accessories
Shielding gas buying guide — Argon/CO₂ mixtures for mild steel, pure Argon for aluminium, and specialist mixtures for stainless.
Welding torches, tips and consumables buying guide — choosing MIG and TIG torches, matching contact tips to wire diameter, and which wear parts to replace most often.
Safety and extraction
Welding helmets, gloves and PPE buying guide — auto-darkening helmets, process-matched gloves, welding jackets and essential workshop safety products.
Fume extraction buying guide — extraction arms, mobile units and centralised LEV systems, plus personal exposure monitoring.
Buying considerations
Consumable quality, value and cost — branded vs generic, premium vs budget, whether cheap consumables are a false economy, and how to reduce welding costs without reducing quality.
Stocking and standardising welding consumables — what to keep in stock, buying in bulk, standardising across a workshop, and building a fabrication starter kit.
Choosing the right process and supplier
Choosing the right welding process for your work — which process suits production, precision, stainless, aluminium, structural steel and beginners.
Choosing a welding consumables supplier — what to expect from a supplier, the value of technical support, and why a long-term relationship pays off.
