IGBT Inverter Pulse TIG Welding Machine (WSM7-500)
The IGBT Inverter Pulse TIG Welding Machine, Model WSM7-500, is a high-performance welding system designed for professional and industrial use. It supports DC TIG, pulse TIG, and MMA welding, making it a versatile choice for various applications. The machine is equipped with advanced safety features such as automatic overcurrent, overheat, and over/under voltage protection, ensuring reliable and safe operation.
Key advantages include an easy arc-start function, stable arc performance, and concentrated heat distribution, which contribute to efficient and precise welding results. The adjustable parameters—such as peak and bottom values of pulses, pulse frequency, duty cycle, and maintaining current—allow users to customize the welding process according to specific needs.
This model inherits all the essential functions from the WS7 series, offering enhanced performance and user-friendliness. The power source operates on a 3-phase input of 380V/415V/220V at 50Hz, with a rated input capacity of 23.7 KVA and a rated input current of 36A. The machine delivers a maximum welding current of 500A, with an adjustment range from 20A to 500A. It operates efficiently with an efficiency rate of 83%.
For TIG welding, the no-load voltage ranges between 40-50V, while for MMA welding, it ranges between 70-80V. The machine also allows users to adjust the current up/down-slope time from 0 to 10 seconds, and it includes pre-gas and delay gas sending times of 1 second and 5 seconds respectively. Arc starting is achieved via HF (High Frequency) technology.
Overall, the WSM7-500 is an ideal solution for welders seeking precision, reliability, and flexibility in their work.
