## Questions & Answers

**Q: Does anyone know if Airgas will refill or exchange these 125cf tanks without issue?**
A: Yes, I heard so. They are DOT approved.

**Q: What are the weights of the tanks?**
A: 40CF  36lbs, 80CF 52lbs, 125CF 72lbs

**Q: Also having problems removing cap looks like it’s cross threaded. Any suggestions**
A: I would tap it with a rubber mallet from side to side to break rust loose. It probably is stuck from any surface rust or were they painted the bottle. Just keep tap and working a little back and forth till you break it loose.

**Q: How long can i weld with this tank?**
A: It depends on the gas flow rate for the material that you are welding. For example, if you are tig welding stainless steel with a gas flow rate of 20 cfh(cubic feet per hour), then this tank will last for 2 continuous hours of welding.  Most weld jobs take a couple of minutes of gas flow so if you only weld small jobs and use the gas flow for 5 minutes a week, this tank will last you about half a year (24 weeks).
