This 15kg spool of A18 SG2 MIG wire is formulated for superior arc stability. The 1.0mm diameter is ideal for medium to heavy fabrication work. The copper coating reduces friction in liners for smooth feeding. The precision winding prevents memory curl that can cause feeding issues. The ER70S-6 classification ensures consistent weld quality. The low spatter formulation minimizes post-weld cleanup. The heavy-duty steel spool withstands shop conditions. Ideal for flat and horizontal position welding on carbon steel. Produces clean, strong welds with excellent mechanical properties. Packaged to prevent moisture absorption during storage. A reliable choice for professional welding operations.
