I am extremely impressed with this welding machine .Based on my experience it is a heavy-duty welding machine that delivers excellent results. It is very easy to use and its compact size makes it perfect for both home and industrial use. The portable function allows me to carry the machine to different locations. the only downside is that it can get quite hot during prolonged use. Overall, I highly recommend this welding machine for anyone looking for a reliable and durable option for their welding needs..
