Hi all, My gas rep. just stopped by and brought me what he says is the
correct regulators for the mini torch. They are Smith Light Duty
H1941E-520. Designed for low pressure use (tip size 3-5, pressure 3-5)
His name is John Niemeyer at Twin City Oxygen 651-628-4848.
What a relief to without a heartbeat in my flame!
