What package types are available?

Spool and drum packages are available, with aluminum-foil vacuum sealing and desiccant inside. Complete labels show model, batch number and net weight for full traceability, compatible with various wire feeders.

How about wind-resistance for outdoor welding?

Better wind-resistance compared with gas-shielded wires. Simple wind-shield measures are still suggested under strong wind to guarantee weld quality.

What polarity should be used?

DC- (Direct Current Straight Polarity). Adjust polarity according to welder manual. Wrong polarity will result in unstable arc and heavy spatter.

Product Q&A

Q:Do I need shielding gas for welding with this series wires?

No. These are self-shielded flux-cored wires. No external shielding gas such as CO2 or argon is required. Use dedicated self-shielded welder for welding, ideal for field sites without gas supply.

Q:Is all-position welding available?

Yes. It supports flat, horizontal, vertical, overhead and vertical-down welding. Excellent performance for vertical-down welding, especially for field girth weld of pipelines.

Q:What are the storage requirements?

Store in dry and ventilated warehouse, keep away from moisture and corrosive substances. Keep original aluminum-foil vacuum package sealed before opening. Once opened, use as soon as possible to avoid moisture absorption and welding porosity.

Q:What causes porosity defects?

Mostly caused by damp welding wire, unclean base metal with rust, oil or water, or improper welding parameters. Keep wire well-sealed, clean workpiece surface before welding, set proper current and voltage to improve weld quality.

Q:Is it suitable for indoor precision stainless-steel welding?

Not recommended. This series is designed for carbon steel and low-alloy steel for steel-structure and pipeline projects. Please use dedicated stainless-steel gas-shielded wires for stainless steel welding.
