CONFORMANCES AND APPROVALS:
• AWS A5.18, E70C-6M H4
• AWS A5.18M, E48C-6M H4
• ASME SFA 5.18, E70C-6M H4
• CWB, 90% Ar/10% CO2, E490T15-M20A3-CS1-H4 (E492C-6M-H4)
• CWB, 75% Ar/25% CO2, E490T15-M21A3-CS1-H4 (E492C-6M-H4)
• 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, either short circuit or pulsed welding current must be used.
• See Above: This information was determined by welding using 75% Ar/25% CO2 shielding gas with a flow rate between
35-50 cfh (17-24 l/min). For the lower CO2 shielding gas mixtures within the recommended range, reduce listed voltages by 1-3 volts.
