INTRODUCTION:
CHAMP MIG 400 is an IGBT inverter based welding power source, suitable for GMAW applications. The IGBT Power module, high frequency transformer and fast recovery diode are used as key devices for power conversion and transmission to assure better efficiency and performance. The complete system consists of power source, wire feeder, gas cooled torch and inter connecting cables.
PROTECTION:
The equipment is provided with following protections.
A) Under Voltage and Over Voltage: If supply voltage goes lower or higher than set limit, error message is displayed on Display.
b) Over Temperature: If the temperature of the main power elements is more than safety limits, error message is displayed.
C) Single Phasing Protection: If any one of the three phases (R,Y,andB) is absent, welding will stop. Welding current would not be available in this condition.
FEATURES:
- Digital Panel for adjusting the welding.
- 25% more Energy efficient than conventional machines.
- Maximum Power factor is 0.95.
- Excellent dynamic response enables superior arc characteristics.
- 2T, 4T operating modes.
- Dynamic Inductance adjustment for better arc control.
- Crater voltage and Crater current adjustment through digital panel.
- Unique feature of Pinch-off pulse to avoid globule formation.
- Automatic “Weld Stop” facility.
- Normal/ Creep feeding selection available on front panel.
