Yes, the Force welding machines can be connected to a motor generator (with a recommended power of at least 3kW for the 125 model, 5kW for 145, 6kW for 165 and 168, 7kW for 195). The motor generator must also supply a voltage within a range not lower and higher than +/ -15% of the welding machine power supply, i.e. 230V. (between 195.5V and 264.5V).
