I did most of my welding outside or in a rented workshop. Storing and using CO2 is a different matter especially as CO2 is far less hazardous and is actually used in fire extinguishers.

FFS welding a camper van is not Sellafield - my CO2 railings etc show no signs of failure - what degree of *can't use CO2* are you still defending??? Cheers Jim K

AD loves the book theory so much he swallowed it, but it just keeps coming back up when not needed.�

As to Jim K, then if he thinks "good enough to weld railings" is good enough to repair a suspension tower, then I hope he has a careful MOT tester who fails what needs failing. |
