Consumables Detail

Use with Ar+0.5-5% CO2 or Ar + 0.5-3% O2 mixture shielding gas;
Axial spray arc transfer, high deposition rate easily achieved;
Low susceptibility to hot cracking & high resistance to intergranular corrosion;
Excellent weldability - Stable arc, low spatter, good wetting and fl­uidity brings outstanding bead appearance
Superb feedability - Unique manufacturing technology results in an even clean wire surface, stable wire feeding and low contact tip abrasion.
