Description
Characteristics:
LKT-75 is designed for welding of low alloy and 590N/mm2 grade steel. Commonly used is butt or fillet welding. It can be operated with a wider range of welding currents.
Applications:
It is suitable for welding of high strength steel used in vehicles, buildings and bridges
Notes on Usage:
1.Electrode Stick Out must be kept between 15-25 mm.
2.Use 100%Ar₂ as shielding gas.
