Notes on Usage

Sizes Available and Recommended Currents (Amp.)

SM-55H is a solid wire for flat and horizontal fillet welding and is to be used in high current

welding with CO2 shielding gas. It benefits from a high deposition rate and excellent penetration.

As this wire contains special elements, its weldability and impact values are excellent.

Use welding grade CO2

Shielding gas flow rate should be 25 /min

Use wind screen against wind.

Keep distance between tip and base metal of 6~15mm for less than 250A, and 15~25mm for

more than 250A of welding current.
