IGBT Based Solid State Inverter Design: Latest technology used for full bridge topology to ensure reliable, superior weld control every time.
Portable: It is very portable at 12 Kgs. (basic inverter) operator can move from one place to another place without any difficulty.
Low OCV: During energy saving, OCV goes down to as low as 20 VDC for added safety and energy saving.
Adaptive Soft Start: Sigma Weld ensure the wire feed speed is automatically controlled from a slow start to the set current and voltage levels to eliminate globule formation at the end of wire and gives clean start each time.
Single Increment Range: Digital front panel allows the operator to set the current and voltage is required in single increment also.
Crater Current & Crater Voltage: Programmable Crater Current & Crater Voltage settings for smooth weld finish.
Safe and Reliable: Low OCV and protection against prolonged Output Short, IGBT Over Current, IGBT Short Circuit Current, Welding Over Current, Thermal Overload.
Power Fluctuation Compensation: Power source does not get affected and it remains constant regardless of fluctuation in input power + 15%. It is suitable especially for the Indian Industry.
Digital Reading: During welding, it continuously monitors and displays weld current and weld voltage.
Selectable Post Flow: One touch button setting for 3 sec., 10 sec., post flow timing.
Versatile: Sigma Weld can weld using welding wire sizes from 0.6mm to 1.60mm.
Process Memory Recall: Sigma Weld ensures faster setup time between processes and on each power on by remembering the settings for each and every process individually.
Energy Saving Mode: When operator is not welding for 2 minutes, then welding inverter in Manual / Stick mode goes into energy save mode, enabling saving of unwanted energy loss.
Settable weld stabilizer: (settable inductance) provides the flexibility to produce the optimal arc characteristics with smoother current for different types and sizes of welding wires.
External Wire Feeder: Compact and portable external wire feeder with 4 x 4 feed roll mechanism to guarantee study uninterrupted wire feeding.
