Product type
Transformer welding machines are a type of arc welding equipment that utilize a transformer to convert high voltage into low voltage for welding applications. These machines are typically constructed with robust metal casings and feature a transformer core that regulates the electrical current. They are commonly used in various welding processes, such as stick welding, to join metals effectively and efficiently.
| Power output | 100 to 400 amps |
| Input voltage | 220V to 440V |
| Duty cycle | 20% to 60% |
| Weight | 50 to 150 kg |
| Cooling method | Air-cooled or fan-cooled |
When choosing a transformer welding machine, consider the power output required for your specific welding tasks, as well as the input voltage compatible with your power supply. It's also important to evaluate the duty cycle, which indicates how long the machine can operate before needing to cool down. Buyers should specify any necessary certifications or compliance with industry standards, as well as the quantity needed for their operations.
