MIG/MAG Welding Wires — Mild Steel, Stainless, Aluminium, Flux-Cored

MIG = Metal Inert Gas (uses pure argon or argon-helium shielding gas — preferred for aluminium, copper, stainless). MAG = Metal Active Gas (uses CO2 or argon-CO2 mix — preferred for mild and low-alloy steel because CO2 contributes to weld pool chemistry). In practice, the wire is the same — what changes is the shielding gas. Ador Automig wires work for both MIG and MAG depending on the gas you pair them with. For mild steel ER70S-6, common gases are 100% CO2 (cheapest, more spatter), 80/20 Ar/CO2 (less spatter, cleaner weld), or 90/10 Ar/CO2 (best appearance, more expensive).

Three common choices: (1) 100% CO2 — most economical, produces more spatter, deepest penetration, suitable for thick plate and structural work where appearance is secondary; (2) 80/20 Ar/CO2 — balanced cost-quality trade-off, less spatter than pure CO2, smoother weld appearance, standard for production fabrication; (3) 90/10 Ar/CO2 or 95/5 — premium gas mixes for highest appearance quality (architectural welding, visible automotive welds), highest cost. Most production shops standardise on 80/20 Ar/CO2 as the best overall balance.

Standard spool sizes: 12.5 kg (most common), 15 kg, 17 kg. For high-volume production we supply bulk drums of 200-300 kg (with appropriate drum-feed equipment compatible with your wire feeder). Drum supply reduces wire-change downtime in 24/7 operations. We coordinate drum equipment if you're new to drum-fed welding.

Store in original sealed packaging in a cool, dry environment (15-25°C, <60% relative humidity). Once opened, use within 2-3 weeks — air exposure causes surface oxidation that affects wire-feed smoothness and weld quality. For wires sitting in feeders idle for >24 hours, retract back to spool and re-seal in moisture-barrier bag. Most quality issues we see with MIG welding trace back to oxidised wire from prolonged exposure or improper storage.

Yes. We stock E71T-1 (mild steel, 70 ksi tensile, all-position, requires CO2 shielding) and E81T-1 (high-strength low-alloy, 80 ksi tensile). E71T-1 is the workhorse for shipyard plate welding and outdoor structural fabrication where MIG wire would have shielding-gas issues (wind, breeze). Spool sizes 12.5 and 15 kg. Bulk drums of 200 kg available for high-volume sites.

Yes. Ador Automig wires are widely qualified for robotic welding installations across Indian auto-ancillary (Bharat Forge, Sundaram-Clayton, Mahindra CIE). Wire diameter consistency and cast/helix tolerance are critical for robotic feed smoothness — we supply with strict tolerance certification on each spool. For new robotic installations, we recommend a process-qualification batch (typically 200-500 kg) before bulk rate-contract supply to validate feed smoothness in your specific robot/feeder/torch setup.
