Hardox weld should be used using soft electrodes.(Yield Strength Less than 500N/mm2).If your weld subjested to heavy wear it is recommended to use the hard facing electrode for the cap beads. Hardox is weldable using the following electrodes. SMAW - E7018/E7028/E8016 SAW - F7Ax-xx MIG/MAG - ER70-x FCAW - E7xT-x Hardox 400 40mm combined thickness will need 75°C preheat and the interpass temp should be kept to 150 - 175°C. If preheating is a problem it is possible to weld without preheat using a 309L type electrode or wire, but remember stainless cannot be burned with standard oxy-acetylene.
