1. Components: Good-quality welding machines use imported IGBTs, branded capacitors, all-copper wire transformers, and large-size heat sinks. Poor-quality welders use domestic IGBTs, secondary recovery capacitors or refurbished capacitors, aluminum wire transformers, and small-sized heat sinks.
2. Performance: Good-quality welders have sufficient power, a high duty cycle, and can work continuously. The duty cycle of poor quality is low. After using a few welding rods, the machine will be protected, and it will take a while.
