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 equally works well on generator sets with balanced load.
2.Water Cooling Unit Interlocking
Sigmaweld WCS (Water Cooling System) can be easily counted 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 code. No more torch burn out due to no water flow
3.Smart Operations
If the operator runs 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 tungsten touches the job, the welding current and voltage are stopped immediately and helps to avoid tungsten son defects
Protections and Safety and IGBT peak current locking. This ensures longer life equipment.
4.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
5.Foot Pedal With Current Control
Potentiometer based remotes or foot controlled remo or adjusting welding current during welding. This hel welder change current while welding as per the nee without using a helper. Our latest foot switch comes wi current control.
6.Welding Automation Accessories
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.
