Why Choose MIG (MIG/MAG)?

MIG welding uses a continuously fed wire and shielding gas for high deposition rates, clean beads and minimal cleanup. It’s ideal for automotive, fabrication and general manufacturing on mild steel, stainless and aluminium. For outdoor work or thicker sections, see flux-cored (gasless) wire.

How to Choose a MIG Welder

  • Amperage & duty cycle: match to material thickness and duty requirements.
  • Power: 230V single-phase for mobile/light fab; 400V three-phase for production.
  • Controls: synergic programs speed setup; manual gives fine control.
  • Wire size: 0.6–0.8 mm for thin sheet; 1.0–1.2 mm for heavy work.
  • Extras: spool-gun ready for aluminium, 2T/4T trigger, inductance control.

Get Better Results with the Right Consumables

Pair wire and gas to the job (e.g., ER70S-6 + C25 for mild steel; 5356 wire + pure argon for aluminium). Replace tips and liners regularly to prevent burn-backs and bird-nesting. Keep anti-spatter handy to reduce cleanup and protect shrouds.

FAQs: MIG Welding

What gas do I need for MIG welding mild steel?

Most users run a 75/25 argon/CO2 mix (C25) for smooth arc and low spatter. Straight CO2 gives deeper penetration but more spatter.

Can I weld outside without shielding gas?

Yes—choose flux-cored (gasless) wire for outdoor/dirty conditions. Expect a little more slag and cleanup.

Which wire diameter should I pick?

0.6–0.8 mm for thin sheet/auto body; 1.0–1.2 mm for thicker fabrication and higher deposition rates.

Do I need a spool gun for aluminium?

Recommended for softer aluminium wires to avoid feeding issues on long liners. Check your machine is spool-gun capable. U groove drive rolls and teflon liners are key to feeding aluminium mig wires.

How often should I change contact tips and liners?

Change tips at the first sign of burn-back or inconsistent feed; liners when you see drag, bird-nesting, or visible contamination.
