I agree with all the previous posts and will add the following information. I have three torch setups including one in the shop, another in an enclosed welding trailer, and one like Tater's in the back of a truck. Life expectancy is the same for all torches. The one in the truck bed, I try to cover up with 5 gallon pails over the regulators and cylinders as well as a scoop shovel over the torch in bad weather. This does not always happen because of details that will not be disclosed here. Back flash arrestors have created a problem in cold weather in the past, but the easy solution was to quit using them. Therefore I would not upset the family with placing the torches on the homework/dinner table.
