Product Description

Feature & Use:

( 1 ) For 490, 520, 540 MPa high tensile steel, this solid wire is designed to operate in high current & high interpass temperature.

( 2 ) Containing special alloy, it performs well in high interpass temperature and lower your cost.

( 3 ) Stable arc, small splash, good performance in high current, best for beam, pillar welding.


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.
