Hi! I’m from the Philippines, and there’s probably 1 in 1,000 jewelry makers here who uses oxy-lpg for their torches so this community is my best bet to ask questions and get answers.
I bought a set of smith little torch with regulators included and another pair of regulators last Dec 2018 from Rio Grande. Since I had to have them shipped here to the Philippines, I was only able to try them recently. My question is, is it normal for the pressures drop from 8 psi to 5 psi when I open the valves of the torch? By the way, the regulators are single stage.
Also, I have messaged Rio Grande 4 times, but I get no reply.
