Specifications:
DESCRIPTION AND APPLICATION
- MIG-308L is designed for 100% CO2 gas shielding and all-position welding.
- It exhibits excellent slag detachability.
- And almost spatter-free operating features can be used for joining of austenitic steels such as Types 304, 304L, 321, CF-8, and CF-3.
- It also provides better inter-granular corrosion resistance due to a low carbon weld deposit.
- Before welding, the base metal should be cleaned from oil, rusty, moisture and the welding place should have the proper protection from the wind.
- Use 99.8% purity or higher CO2 shielding gas.
- Maintain the flow rate not less than 20L/min when wire diameter is 1.2 mm.
- Trailer Shield is required to ensure the weld pool completely shielded until solidification is complete and no porosity problem.
- Keep dry while in storage and delivery.
