Description
Characteristics:
LKM/LKT-309LMo is a modified type of LKM/LKT-309L with the addition of molybdenum. It
designed for 100% CO2 gas and all-position welding. It performs with smooth arc transfer, low spatter level,
fast freezing slag and, good heat and corrosion resistance.
Applications:
It is suitable for welding stainless steel to unalloyed steel. It is also used for buffer layers of clad
steels.
Notes on Usage:
1. For TIG process, use DC(-) current , Argon Shield and Tungsten Electrode.
2. For MIG process, use Spray Transfer or Short Circuit Transfer mode.
3. 98%Argon – 2%O2 shielding gas is recommended in MIG process.
