STANDARD DIAMETERS AND PACKAGES:

• Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical depending on the type and thickness of steel being welded.
• Pulse waveforms are designed with nominal operating points that may result in average voltage and current values that differ from the above table. Generally, pulse processes can be expected to produce lower heat inputs than a standard CV process.
• For out of position welding, short circuit or pulsed spray transfer mode must be used.• See Above: This information was determined by welding using 90% Ar/10% CO2 shielding gas with a flow rate between 35-50 cfh (17-24 l/min).

For the higher CO2 shielding gas mixtures within the recommended range, increase listed voltages by 1-3 volts.

When welding using the 95-99% Ar/Balance O2 shielding gas requirements of AWS A5.28/ A5.28M, decrease listed voltages by 1-2 volts.
