Hello everyone!

I got a sievert torch about a year ago, and initially had some problems with it bursting into flames where the nozzle attaches. I sent it back to the company I bought it from to have it checked over. The problem was simply that the nozzle was not screwed on tight enough allowing gas to escape. The company very kindly tightened it up for me and I had no problems until now.....it has started bursting into flames again and I found the nozzle had loosened drastically. I am having trouble tightening it sufficiently, and just wonder what tool(s) anyone uses/would recommend for tightening the nozzle effectively? I am reluctant to use it until Im sure it is safe to do so!!
