What should welding gas regulator be set at?
Press the trigger on the MIG gun to activate the gas valve. Read the PSI on the left regulator gauge; it should read between 25 and 30 cubic foot-hours.
Are Argon and Co2 regulators the same?
Generally, the Carbon Dioxide regulator is the same as Argon/Co2 regulators. The main difference besides the looks is the fitting of the regulator. Instead of being with male thread as it is argon regulators, for Co2 it is female. That is because the Carbon Dioxide cylinders have a female fitting.
What is the standard psi for the welding gas?
MIG shielding gas flow is set and measured as cubic feet of gas per hour (CFH) NOT pressure in psi. Unlike oxyfuel welding and cutting, MIG gas flow rates are very low. The gas pressure in the hose going into a wire feeder/welder, while welding, typically varies from 3 to 8 psi.
Do you need a special regulator for argon gas?
Argon Regulators normally show Gas Flow Rate in Litres Per Minute and Cubic Feet Per Hour. An Argon Regulator should also be used for Argon/Co2 Mixed gases.
Can you use CO2 for MIG?
The most common of the reactive gases used in MIG welding is Carbon Dioxide (CO2). It is the only one that can be used in its pure form without the addition of an inert gas. Pure CO2 provides very deep weld penetration, which is useful for welding thick material.
Can you use CO2 for MIG welding?
The most common of the reactive gases used in MIG welding is Carbon Dioxide (CO2). It is the only one that can be used in its pure form without the addition of an inert gas. CO2 is also the least expensive of the common shielding gases, making it an attractive choice when material costs are the main priority.
What gas do I use for aluminum spool gun?
argon
Choose the right gas: Because aluminum is a non-ferrous metal, it requires a 100 percent argon shielding gas. Flow rates of 20 to 30 cubic feet per hour are recommended.
What should gas flow be for MIG welding?
20 to 25 cubic feet per hour
MIG welding requires DC electrode positive, or reverse polarity. The polarity connections are usually found on the inside of the machine. Set gas flow. Turn on the shielding gas and set the flow rate to 20 to 25 cubic feet per hour.
How many CFM do I need for MIG welding?
Comments for correct cfm for mig welding if using 3/8 inch nozzle minimum cfm is 15 with 18-22 cfm is in normal range 30 cfm being the maximum setting.
