MIG|MAG|FCAW  Digital Welding Inverters

Features :

1. Constant Current Output Provided

The output of sigma Weld welding inverters are constant even if there is a power fluctuation in the mains of upto +/- 15%. The power of source works equally well with Generator Sets with balanced load.

2. Protections and Safety

Sigma Weld welding inverters are designed for Safety of both operator and machines, It has inbuilt protections for Overvoltage, Undervoltage, Output Short, Thermal Overload and IGBT Peak Current locking. This ensures longer life of equipment.

3. IGBT Based Solid Inverter Design

Latest technology used for full bridge topology to ensure reliable, uperior eld control everytime. The new Multilayer control card design ensure noise immunity and rugged inverter design.

4. Voltage and Speed Lockable parameters* :

With advanced micro-controller technology it is possible to lock the Voltage and Current Parameters to desired level by the Supervisor,ensuring complete run at desired WPS parameters without changes by the Operators.

5. Easy to learn Easy to Weld parameter setting

Simple design for ease of operators, settable parameters such as Welding Voltage, Wire Feeding Speed, Crater Voltage and Crater Wire Feeding Speed can be adjusted from the Panel or Wire feeder. The SigmaWeld welding Inverters can be used in 2T/4T mode.
