Tianyu welding machine inverter DC arc welding machine zx-3 15 can use 220v electricity?

I am a welder. Although I have never heard of Tianyu, all the machines of zx7-3 15 can use 220 household appliances, but this one is a little more expensive than the single voltage one, that is, 50 yuan more. You can search the Ruihong welding machine I made, as well as Hanwang's, which has a national warranty and agents in all regions, but if you sell it, I can.
