Can argon arc welding machine be used as cutting machine?
No, it can be used as an electric welder. You want to make a cutting machine. Buy a plasma bar with that!
It should be possible to change the gas to compressed air and adjust the current to the extent that it can be burned through the material. These have to be tested for long experience. In addition, argon saves some of the possible tungsten charges, and uses argon and tungsten to save some. You can change the electrode during the test to see if the effect is better.
May not。Argon arc welding can not be used as plasma cutting machine. It is also impossible to weld the parent metal with tungsten.
