Gas bottles (cylinders of CO2, O2, Ar, acetylene, and MIG mix) in the Welding Zone are refilled by members

If a cylinder runs out while you are using it, take it to be refilled or mention it on Slack.

Take the tank over to one of the shops (Linde/PraxAir on Dequindre near 13 mile recommended)
Leave the tank in your car
Go into the store and tell the counter person you are with i3 Detroit (we're tax free) and you need to swap out an acetylene tank
Per their instructions, drive around, do the swap
Go back inside to pay (if you know the size, you can pay prior to the swap
Take a picture of the receipt and go to i3detroit.org/reimbursement and do the thing, if you want to get reimbursed. If you'd rather it just be a donation, skip this step

If you can't float the money, reach out to the Treasurer to arrange having them call and pay over the phone.
