Mig gas pressure

admin

Hello..New to the site here...I picked up a Lincoln 175HD for a good price and I just got back from picking up a bottle of 75/25 mix, now how do I know what to set the gas regulator at? I fired it up and even with the regulator cranked down low, it sems as though there is quite a bit of gas coming out.ThanksRich
Reply:Hello. Migs are set using cubic feet per hour, not PSI. Most mig "regs" ( they are actually flow meter's not regulators) will read in CFH or if metric, liters. Usually 15-20CFH is the "norm", but if welding outside you might need to go higher to get enough shielding gas to protect the weld. Inside you may be able to turn down the "reg" a bit if welding in tight quarters where the gas gets "trapped". It's all about having enough gas coverage to prevent porosity.Note that some cheap  flowmeters are preset and you simply can't do anything to adjust the flow..No government ever voluntarily reduces itself in size.

Reply:Read the manual and learn how to install and operate regulators.  Conventional flow-gauge regulators are cranked OUT for low.  Cranking "down" or in increases pressure/flow.  You only want about 20 CFH on the low pressure dial."USMCPOP" First-born son: KIA  Iraq 1/26/05Syncrowave 250 w/ Coolmate 3Dialarc 250, Idealarc 250SP-175 +Firepower TIG 160S (gave the TA 161 STL to the son)Lincwelder AC180C (1952)Victor & Smith O/A torchesMiller spot welder
