Sigma Weld MIG : Welding Inverters From Electronics Devices
 

Sigma Weld series welding machines are sophisticated IGBT based inverters with total digital control having wide current range. Sigma Weld is designed to meet varied requirement of the welding industry with MIG welding inverters for 170A, 400A and 500A range. Advanced micro controller technology enables Sigma Weld to have excellent soft start, digital display for both current and voltage, adaptive adjustable inductance for both 2T and 4T operations, crater current and crater voltage features. Separate wire feed units can be mounted on the inverter or taken to work location with longer interconnection cables for added flexibility to the welder. Sigma Weld automatically controls the wire feed speed to suit the set current and voltage levels and ensures smooth welding with finer control repeatedly.
 
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.
