Xiang Welding Industrial Co Ltd
A 120,000 psi tensile, high performance metal cored wire for use with high strength, low alloy steels such as ASTM 514, HY-100 and T1 steels. Diffusible hydrogen levels will be less than 4ml/100g of deposited weld metal giving it more resistance to cracking.

CONFORMANCES AND APPROVALS:
• AWS A5.28, E120C-K4 H4
• AWS A5.28M, E83C-K4 H4
• ASME SFA 5.28, E120C-K4 H4
• EN 18276: T 89 4 Mn2NiCrMo M M 1 H5
• 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.
• See Above: The information above was determined by welding using 80% Ar/20% 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.

FEATURES AND BENEFITS
• Unique seamless wire manufacturing process 
• Metal-cored wire that provides higher deposition rates than solid wires
• Seamless wire provides low hydrogen electrode wire very low moisture pick-up
• Very high tensile strength weld deposit
• Excellent wetting and gap-bridging capabilities
• Can be used out of position with pulse-capable welding
• Provides very consistent chemical and mechanical properties• Allows increased travel speeds and productivity
• Minimizes risk of hydrogen cracking, even after considerable atmospheric exposure • Suitable for many quench & temper (Q&T) and high-strength low-alloy (HSLA) steels
• Suitable for use in automated and mechanized applications, as well as root-pass welding without use of backing
• Minimizes the number of products required for complex weldments
