The mig gas diffuser is a small part in the welding torches .But it is very useful .The gas diffuser can shunt , and partial pressure .It increased the safty of the use .The mig gas diffuser also has two normal material :the DMC and the ceramic,but we have a new greatest material red Silicone Rubber material, it used in 350A,24KD,36KD.
In the color ,you can see White,Pink,Red,Black.The custom can choice depend on the torches they used .They are suit for all the mig welding torches.
