Product Description

AWS ER120S-G is a specification for a type of steel filler wire used in welding. The "ER" stands for "electrode or rod," the "120" indicates the minimum tensile strength of the weld metal in thousands of pounds per square inch (psi), and the "S" indicates that it is a solid wire. The "G" at the end of the specification indicates that the filler wire is used for the gas metal arc welding (GMAW) process.

This MIG wire meets ER120S-G standard is a high strength alloy steel commonly used in automotive repair. It is a wire that we manufacture in China and is a direct replacement for Bosch DS980J and an excellent replacement for Böhler Union X96 and Titan Tech EQ-5029X96. The wire meets the welding requirements of American Honda's ProFirst collision repair facility for high strength steel.

The wire is specifically designed to weld high strength steel joints of 590 MPA or higher. It has a high nickel, manganese, silicon and molybdenum content for excellent welding results in critical high stress, fine grain applications. It has a tensile strength of 140,000 PSI (980+ MPA), uses argon/CO2 shielding gas and meets AWS A5.28 ER120S-G standards.

AWS ER120S-G - Feature & Use

AWS ER120S-G - Notice

1. Please use specialized welding gas, eg: purity of CO2≥99.5%,H2O≤0.005%,Ar≥99.99%. Gas flow: 20~25L/min.

2. Wind affects arc and welding pool, please take steps to block the wind.

3. There is smoke when welding, pay attention to ventilation.

4. Distance between Tip and base steel is about 15mm when current is below 250A; and 20~25mm when current is above 250A.

5. Welding materials should be stored in dry places.

6. Please check the welder ,wire feeder, gas regulator and heater before operation.

7. Please keep the percentage of mixed gas stable and keep gas pressure stay the same.

8. As to thin steel plate, downward welding in the inclined position or forward welding is recommended,(pictures are followed below).

9. Please move plastic spool and basket spool in a correct way.
