The is a vintage, European-built single-phase transformer MIG welder designed for light industrial, automotive repair, and hobbyist metalworking applications . Manufactured by the respected Italian brand CEM (historically associated with the Cemont group), this machine is highly regarded for its rugged all-metal construction, traditional heavy-duty step-regulated copper transformer, and dual-purpose capability.

Often available at a low cost on the used market (around €200–€250). : Heavy and bulky compared to modern inverter welders. Limited technical support and spare parts.

A common failure point is the drive motor or the speed controller on the PCB. If both the arc and feeder fail, it often points to a fault in the auxiliary power supply or the torch trigger switch. The “CEM Dual MIG 140T” isn’t just a

⚠️ Real-world max on 110V is about 100-120A; 220V is needed for full 140A.

Remove the contact tip from the gun before feeding; replace it once the wire exits the nozzle.
