Low Voltage Short Circuiting-GMAW

The voltage range used is generally the best guide to GMAW-S. A low voltage is one of the reasons that GMAW-S does short circuit. If the shielding gas is CO 2 or an argon CO 2 mixture, the filler metal diameter is 1/16 inch diameter or less and the voltage is 22 volts or less, the GMAW process is most likely in the short circuiting mode.
