What does a welding regulator do?
The main job of the welding pressure regulator is to control the pressure of the gases used in oxyfuel welding. For example, the pressure acetylene gas is under in the cylinder is typically more than seven times greater than the pressure of the gas in the torch.
What kind of regulator do you use for MIG welding?
Argon Regulators normally show Gas Flow Rate in Litres Per Minute and Cubic Feet Per Hour. It’s important to make sure the Delivery Gauge reads Flow Rate as most Mig and Tig Welders will quote a recommended delivery in Litres per Minute. An Argon Regulator should also be used for Argon/Co2 Mixed gases.
Can I use a argon regulator for nitrogen?
A nitrogren regulator used for Nitrogen and Argon – it will fit both tanks. A nitrogen regulator has a higher high-pressure gauge than a CO2 regulator. (The starting pressure in a Nitrogen/Argon tank will be about 2200 p.s.i. as opposed to 800 p.s.i for a CO2 tank.)
What’s the difference between a regulator and a flow meter?
While both are designed to regulate pressure and measure gas flow, they operate quite differently. A regulator flowmeter delivers the gas at a fixed pressure to a variable orifice (valve), and a flowgauge uses variable pressure to deliver the gas to a fixed (drilled) orifice.
Can CO2 be used for 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.
How do you adjust a MIG welding regulator?
If your setting gas flow on a Mig or Tig, operate the machine so it’s gas valve is open. Slowly turn the Gas Regulator Control Knob clockwise. When you start to feel resistance the gas should start to flow and the Delivery Gauge Needle will start to move around the scale.
How many psi is a full argon tank?
2265 PSI

What should the gas pressure be when MIG welding?
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.
Which is heavier argon or nitrogen?
Argon is a denser gas than nitrogen, and an industrial application purged using argon will keep moisture and oxygen out more effectively as a result.
