The CEM Dual MIG 120 is a dual-function welder, capable of performing both and Gasless (Flux-Cored) welding. Without the manual, new users often struggle with polarity settings, wire feed speed calibration, and voltage matching. The manual provides the manufacturer’s exact parameters for:
0.6mm – 0.8mm solid wire (Gas); 0.8mm – 0.9mm flux-cored wire (Gasless). Welding Capacity: Mild steel up to 4mm–5mm thickness. Protection Rating: IP21 or IP23 (standard for workshop use). clarkeservice.co.uk Key Controls and Setup Polarity Selection: MIG (Gas): Torch is positive (+), Ground clamp is negative (-). Gasless (Flux-Cored): Torch is negative (-), Ground clamp is positive (+). Wire Installation:
Like any tool, this welder will last longer with regular care:
