I have been using one set of tanks and regulators to run two smith
mini torches for years now. The regulators are about 5 years old and
seem to be holding pressure just fine. The problem is that my number
4 torch tip, the one I use for most everything is blowing out. I used
to be able to really crank it up for a quick solder. I have tried to
adjust the regulators, that hasn’t helped. When I put a larger tip
on, I get the black soot that acetylene is known for. I am ready to
throw out the regulators and buy some new ones. But not knowing if
that will help, I hesitate to do that. Any suggestions?
Thanks, Janine in Redding.
