SigmaWeld Series welding machines are sophisticated IGBT based inverters with total digital control having wide current range.
The parameters settable are peak current, base current, upslope time, downslope time, gas preflow, gas post flow, torch mode(2 Track, 4 Track), frequency (AC Welding), duty cycle.
If the operator presses the torch switch but does not start welding, the gas solenoid is switched off within 10 seconds. Ensuring no wastage of shielding gas.
The AC mode helps weld materials like aluminium with great ease.
Features:
1)Constant Current Output Provided
The output of Sigmaweld welding inverters are constant even if there is a power fluctuation in the mains of upto +15%. The powersource works equally well with generator sets with balanced load
2)Excellent Welding Performance
The parameters settable are peak current, base current , upslope time, downslope time, gas preflow, gas post flow, torch mode (2 Track , 4 Track ), frequency (AC Welding), duty cycle
3) Protections and Safety
Sigmaweld welding inverters are designed operator and machines. It had inbuilt protection undervoltage, thermal overload and IGET This ensures longer life of equipment
4)Water Cooling Unit Interlocking
Sigmaweld WCS (Water Cooling System) can be easily mounted below the Sigmaweld welding inverters making it one completely integrated unit. The Sigmaweld wcs contains stainless steel tank, radiator and forced air cooling. Interlocking of water cooling unit with the program ensures that the WCS is operational only in the GTAW mode. Further the flow switch ensures that if the waterflow is insufficient then there is no welding. This is tosafe guard the welding torch and operator.
5)Welding Automation and Accessories:
Sigmaweld GTAW machines can be controlled with the help of our standard push button based remotes, potentiometer based remotes or foot controlled remote for adjusting welding current during welding.
Sigmaweld GTAW machines can be interfaced with robots, welding SPM’s and other systems with ease.
Sigmaweld automation systems such as weaving units, AVC (Automatic Voltage Controllers), special purpose machines, cold wire feeders etc are specially designed to enhance productivity and quality of welding
