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.
Energy Saving , VRD Inbuilt
When the operator is not welding for more than 2 minutes, the power source automatically switches to low open circuit voltage output below 24V for safety of operator. This also leads to saving of no load losses.
Excellent Welding Performance
The parameters settable re Peak Current, Base Current, Peak Time, Base Time,Upslope Time, DownSlope Time, Gas preflow, Gas Post flow,Torch Mode (2 Track,4 Track), Frequency(AC Welding)
If the operator presses the torch switch but does not start welding,the Gas Solenoid is switched off within 10 sec. ensuring no wastage of Shielding Gas
In case the tunsten touches the job , the welding current and voltage are stopped immediately,helps avoid Tungsten Inclusion defects
The AC Model helps weld materials like Aluminium with great ease
Protections and Safety
SigmaWeld 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 and our inbuilt Voltage Reduction Circuit which ensures OCV as low as 24 Volts or below when not welding keeps operators safe.
Water Cooling Unit Interlocking
SigmaWeld WCS (Water Cooling System) can be easily mounted below the SigmaWeld Welding inverters making in 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. This is to safe guard the Welding Torch and operator.
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.
