Edge is a metal-cored wire with fewer silicon islands than other metal-cored wires. On clean material, weld bead toe lines are almost completely free of silicon deposits. The weld bead face is virtually free from silicon island deposits. Together with exceptional low spatter rates, Edge will save time and money spent cleaning prior to painting, coating, or plating. The recommended shielding gas is a mixture of argon and carbon dioxide, with a minimum of 75% argon and a maximum of 95% argon. Arc characteristics improve with richer argon gases while spatter and fume levels decrease.

STANDARD DIAMETERS AND PACKAGES: 

For a complete list of diameters and packaging, please contact

• Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical
depending on the type and thickness of steel being welded.
• For out of position welding, short circuit or pulsed spray transfer mode must be used.
• 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.
• 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.
