Hi there, I'm fairly new to soldering but have enjoyed making rings, pendants earrings etc. I'd like to make larger pieces now but find my torch doesn't generate enough heat to solder larger items. I have a sievert pro86 torch with a needle point burner and a variable 0.4-2 bar regulator on my bottle. What do I need to change to get more heat. Burner? Regulator? Sorry if this is a basic question but I'm just finding my way TIA
