Requirements for purchasing welding machines

1. When purchasing welding machine products, you should go to regular manufacturers or large shopping malls to purchase, and you should purchase branded and high-quality products with a high market share. Don't go to small stores for cheap prices, as the quality of welding machines there cannot be guaranteed.
2. When purchasing, check whether the nameplate on the product has the manufacturer's name, production address, specifications, welding current adjustment range, load duration, input voltage and current, and then determine the welding machine you want to buy according to work needs.
3. When purchasing, you can ask the dealer to provide a product quality inspection report or certificate. Because welding machine products are national mandatory certification products, you must confirm whether the product has passed the "3C" certification when purchasing. You can also check it online.
4. When purchasing, be sure to check whether the product has a grounding screw, and the grounding screw connection should be free of paint and well grounded. Check whether the movement is clean and the insulation is damaged to ensure safe use. If necessary, you can also test it.
5. Before purchasing, you can power on and check the operation, conversion and installation of the switches on the panel, the on and off of the power indicator, whether the fan is normal, whether there is abnormal vibration and buzzing sound in the power part, whether there is any odor, whether there is any heat phenomenon such as discoloration on the appearance, so as to ensure the quality of the welding machine and give full play to the performance of the welding machine.
6. If you want to buy a gas shielded welding machine, you should also check whether the accessories are complete, whether the wire feeder is oily, whether the rotation is stable, whether the connecting cable matches the surface insulation, whether there is any damage, so as to ensure the stability of the arc.
