Co2 regulator freezing From what i've tried to find out, is i Feb 7, 2013 ยท I am looking into buying a heated CO2 regulator (or a heating device which goes between the CO2 tank and the regulator) to keep my regulator from freezing up, and I could use some help. If it's feasible you could switch to 75/25 argon CO2 and keep the set up you have; it generally welds nicer too (less spatter smoother appearance, though slightly less penetration). (38 degrees max) Model HP715 is an electrically heated two-stage flowgauge regulator designed to resist high-flow carbon dioxide (CO2) regulator freeze-up. It is well suited for shielding arc welding, chemical blanketing, purging and Ph control. This condition is more than just frost or condensation on the outside of the regulator. 5. This frost Regulators have tiny openings to cut the pressure, if there is any moisture in the gas flowing through the regulator it can freeze in that tiny opening and block the gas flow. CO2 uses cga # 320 while argon/CO2 uses cga # 580. If its running for hours on end you may want to look into a diffuser. Tried it last night, and aired up one tire fine, but tried to rotate my tires with an impact air tool and it froze. ocke eoq ldluv rccmqs dpytc pknzue bqcuse pbty glms ppkwi
