SW1000CV  Digital Welding Inverters

SigmaWeld series of welding machines are sophisticated IGBT based Welding Inverters with total digital control having wide range of applications. SigmaWeld SW1000 - CV is designed to meet the varied requirement of the welding industry having possibilities of use for MIG ,MAG, FCAW, Hardfacing, Arcing and Submerged Arc Welding Applications.

Advanced micro-controller technology enables SigmaWeld to have inbuilt wire feeder drive for MIG/ MAG applications, interconnectivity with SAW trolley and other SPM's. The Power Source has inbuilt features for use in 2T, 4T modes with pre-flow , post flow controls for MIG , MAG, FCAW applications.

Energy Saving vis-à-vis traditional Welding equipments for SAW applications is as high as 40 to 60%

Features :

1. IGBT Based Solid State Inverter Design:

Latest technology used for full bridge topology to ensure reliable, superior weld control every time.

2. Mobility:

At 85 Kgs, with 4 Wheels and 4 Eye Bolts it is easy to move our SW1000-CV to any locations with a lot of ease compared to the traditional equipments (300Kgs).

3. 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.

4. Single Increment Range:

Digital front panel allows the operator to set the current and voltage as required in single increments.

5. Crater Current & Crater Voltage:

Programmable Crater Current &Crater Voltage settings for smooth weld finish.

6. Safe and Reliable:

Low OCV and protection against prolonged Output Short, IGBT Over Current, IGBT Short Circuit Current, Welding Over Current, Thermal Overload.

7. 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.

8. 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.

9. Digital Reading:

During welding, it continuously monitors and displays weld current and weld voltage in all modes.

10. Versatile:

Sigma Weld can weld using welding wire sizes from 0.8 mm to 5.0 mm.

Process Memory Recall:

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. It remembers separately the settings for each and every process. This leads to fast set up time between process changes and each Power ON.
