diamondspark 46 RC is a seamless rutile flux-cored wire for mild steel, suitable for all welding positions and run under M21 or 100 % CO2 shielding gas.
Among the parent materials it covers ASTM A 106, API 5 L, S235JR, S355JR, S235JO, S355JO and S450JO. The seamless sheath keeps moisture away from the core even after longer storage, and the copper coated surface improves current transfer in the tip and the feeding.

On thicker parts and in a cold workshop plan preheating to cut the risk of cold cracking. Do not shorten the stick-out too far, a flux-cored wire needs resistive preheating so the core melts in time.
