Transcription of DWG Stainless Series - Kobelco Welding
1 DWGS tainless SeriesThe perfect flux-cored wires for gauge Stainless steel weldingKobelco s flux-cored wire Series for thin plate Welding :DWG-308L, DWG-309L, DWG-316 LFlux-cored .045 wire is the popular choice for use inhigher current ranges (over 150 amps). This is becauseof its advantage over other Welding processes withsolid wire or stick in terms of arc transfer stability inthis s DWG flux-cored Stainless .045 wire hasexcellent arc transfer in wider current ranges from 80 Ato 220A. This wide current range cannot be achievedin conventional .045 flux-cored wire. Because ofunique wire structure, it provides a stable arc evenbelow 150A, for which.
2 035 flux-cored wire is gener-ally used for gauge DWG can be used instead of the moreexpensive .035 flux-cored wire, saving you substantialmaterial cost. Kobelco DWG is designed for use with100% CO2and 75%Ar-25% CO2shielding gas andcomplies with AWS E308LT0-1/4, E309LT0-1/4 and E316LT0-1 arc transfer and ideal slag formula guarantee thatslag comes off easily, creating a smooth and shiny beadsurface.

Higher deposition rateIts unique wire structure assures a 15%higher deposition rate than regular .045 flux-cored wire. This enables the welder tocomplete the job quickly and economical-ly. (See Fig. 3).2. Cost savings with 100% CO2shielding gasKobelco DWG flux-cored wire performsat its best with 100% CO2shielding gas,especially when used under Failure-free arc ignitionConductive flux (slag) enables re-ignitionwithout clipping off the wire end.
