Notes on usage:

1 . Clear rust, oil, water and other impurities on the weldments before welding.

2. It is recommended to use Ar+(1%-3%)02as shielding gas in MIG welding, and use pure argon as shielding gas in TIG welding.

3. The user should develop an appropriate production welding specifications according to the circumstances.
