Note: 1. protective gas AR + 20% CO2, the mixed gas, gas flow 15-20 L/min. Control arc length during welding to avoid welding defects such as blowhole. 2. When welding, it is advisable to control the length of dry extension of welding wire at 10-18mm. When the current is more than 250A, the dry elongation should be controlled in the range of 20-25mm 3. and the impurities such as rust, oil and water should be thoroughly removed from the welding place

How It Compares
ER100SD is a Ni-Cr-Mo alloy solid wire designed for high-strength, high-toughness applications. It differs from standard carbon steel wires by offering superior mechanical properties and impact resistance at low temperatures. Compared to basic-coated electrodes, it provides better process stability and lower spatter in automated or semi-automated gas shielded welding. It is not intended for use in low-hydrogen applications where a basic electrode would be required.
