ER120S-G / G89 4 M21 ZMn3Ni2CrMo

XINYU High strength steel welding wire Description

Feature & Use：

( 1 ) For 890MPa high tensile steel, containing Ni，Cr，Mo etc，excellent mechanical properties.

( 2 ) Adapt to low-alloyed steel structures according to 890 MPa.

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.

We mainly produce High Strength Steel Wire, Low Alloy Steel Wire, Sub Arc Wire And Flux. Including sub arc wire, welding flux, and electrode wire.
