: Please reply our questions...
: 1-What kind of chemical can be used for masking of the material.?
: 2-Rokide Z always spits.(Altough we adjust all the gas values and clean the dirty nozzle.) What can may be reason of this spitting.?
: 3-Can be done coating on the weld filling materials?

1. There are many masking tapes and spray/brush on solutions commercially available. Also consider mechanical metal masks.

2. High moisture content in rods. Try warming rods in oven for good period of time before spraying.

3. Yes.
