The 5KW model can only carry a 200A inverter welding machine. The welding adjustment can only go up to 3.2, because the current needs are large. If you want to do electric welding and there is no power supply, 1. It is recommended to buy a 5kW generator, the price of which is 2400-2600 yuan. and add an inverter. The DC welding machine of the variable welding machine is estimated at 380-600. This is the lowest cost combination, but the use effect is limited and cannot meet the high requirements and large rods welding 2. It is. It is recommended to purchase a dual-purpose machine for power generation and electric welding, made in China. There are three types: 100A to 190A and 200A. The price of 100A is between 2,800 and 3,200 yuan. It is acceptable to burn 2.5 electrodes. , but the effect of 3.2 is not ideal. The price ofu 190A is between 4,800 yuan and 5,800 yuan. It can burn up to 5 electrodes.
What should I do if the generator continues to burn? Which welding machine is good?
You have not specified the specific model of the welding machine, so you can only use the most common ZX7 -200 welding machine as example, perform the following calculation: ?
ZX7-200: DC manual arc welding machine with inverter; Here are the main parameters of this welding machine:< /p>
Rated output current: 200A;
Rated output voltage: 28V;
Output power rated: 5.6KW;
Rated input power: about 7KW;
It can be seen that a 5KW output motor generator cannot drive a welding machine ZX7-200 designed with sufficient power;
It must drive a ZX7-200 designed with sufficient power. power. Welding machine, it is recommended to configureure a generator of around 10KW;
P=UI, there is only one situation where the generator burns the welding machine, that is -say The power of your generator is too high. The generator is small and the generator load is 80%. If the power generated is not enough for your welding machine, its built-in protection system will reduce the voltage and turn off. is not sufficient and the current increases, your machine will burn out. It is recommended to upgrade to a larger generator.
