Which one of 12V/24V/42V is the motor voltage of your welding machine. (Our spool gun is only suitable for 24V) 2. Whether your welding machine is suitable for this spool gun. (make sure the model number is exactly as we wrote) After you purchase, you need to pay attention to: 1. Adjust the welding machine to the "wire drawing" function when using it. 2. Confirm whether the switch of the spool gun is available (that is, after pressing the switch, whether the motor of the welding torch or the welding machine responds). 3. When you are testing, please help us to open the pressing rod, and then see if the motor will rotate. If the motor wire feed roller is stuck, it is possible that the pressure lever is tight.
