Several points of requirements to pay attention to when purchasing electric welding machines:
One, in the purchase of electric welding machine products, to the Formal production enterprises or shopping malls to buy, and to buy a higher market share of brand-name products. Do not want to cheap to small stores to buy, where the quality of the welding machine can not be guaranteed.
Second, when buying, check the nameplate on the product whether the manufacturer's name, production address, specifications, welding current adjustment range, load duration and input voltage and current and some other content, and then according to the needs of the work to determine their own purchase of the welding machine.
Three, you can ask the dealer to provide product quality inspection reports or certificates of conformity. Because the welding machine products are national mandatory certification products, so when you buy must confirm that the product is through the "3C" certification. You can also check online.
