HH torches are designed to work on tank pressure. There was some discussion re HH and regulators on here a week or so ago. The conclusion was that a minimum of 60 PSI was needed to run a HH reliably but that a few people had managed to get/keep one running as low as 45psi. These were exceptions to the rule. I attribute that to variations in torch manufactureing tolerances. As Dale says, cheapass chinese products have proven again and again to be inferior and dangerous at best and deadly in some cases. Also note that the incident happened with a bad torch that is being replaced. It should not happen again with the new torch and if a new proper hose with clamp is used.
