The gas answer
For the VEVOR 130A Synergic MIG: argon/CO₂ mix for steel; pure argon for aluminium.
Gas choice changes with material: steel runs on argon/CO₂ mixes, aluminium and stainless have their own requirements, and the bottle you rent or buy matters as much as the gas inside it.
Where the money goes
- Cylinder rental or swap-and-go fees — the recurring cost most buyers forget to budget
- Refill pricing varies more between suppliers than the gas itself does
- Bottle size vs usage rate — a bottle that runs dry mid-job costs a trip, not just a refill
