Properties And Applications

Non-copper coated and unalloyed GMA (MIG/MAG) wire electrode, especially produced for welding without spatter or very low level of spatter. Suitable for welding of general structural steels, boiler steels, pipe steels and cast steels. Due to it's special coating provides stable arc and no spatter especially with mixed shielding gases which can be used depending on the thickness. Generally preferred in robotic applications, due to it's high welding performance without spatter and cleaning needs. Also provides cost advantages in cleaning after welding, torch spare part consumptions like, contact tip, spiral, driving wheel, anti-spatter sprey. Due to these advantages preferably used in automotive, machine and steel furniture production.
