Low-pressure gas welding regulator, single stage, Acetylene 0-30 P.S.I adjustment range. UL listed comes with CGA510 tank inlet mount (special order with CGA 520 or CGA 300 tanks mounts additional cost may apply). Has type"A" hose outlet, choose below.. Brass construction with precision diaphragm for accurate pressure flow adjustment in the 5 PSI and below range.  A must for thin gauge sheet welding in low carbon steel or aluminum materials Regulator is standard in our DTGW1000 & DTGW1000DLX master gas weldi The low pressure regulator is different from the standard big box cutting torch kit in that the regulators in those kits will not adjust in a accurate way much below 6-7 PSI. Where, a true low pressure regulator will adjust in the 2 PSI range without any inner cone pulse. This is the real key to controlling a heat effective zone in thin gauge steel & aluminum. 3-year warranty.
