Sigmaweld series welding machines are sophisticated IGBT based inverters with total digital control having wide current range. Sigmaweld is designed to meet varied requirement of the welding industry covering metal inert gas (MIG), (MAG), submerged arc welding and hard facing. Advanced micro controller technology enables sigmaweld to have parameter locking technology which doesn’t allow welders to adjust the parameters beyond the WPS settings.
Significant energy saving vis-à-vis traditional welding equipment’s for all applications.
SigmaWeld PIC Series of MIG Welding is specially designed for less spatters.
1.Constant Voltage Output Provide.
The output of Sigmaweld welding inverters are constant even if there is a power fluctuation in the mains of upto + 15%. The power source works equally well with generator sets with balanced load
2.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.
3.IGBT Based Solid State Inverter Design
Latest technology used for full bridge topology to ensure reliable, superior weld control every time The new multilayer control card design ensures noise immunity and rugged inverter design.
4.Easy to Learn Easy to Weld parameter setting
Simple design for ease of operators, settable parameters such as welding voltage, wire feeding speed, crater voltage and crater wire feeding speed can be adjusted from the panel or wire feeder The sigmaweld welding inverters can be used in 2T/4T mode.
Optional Solutions Available
5.Voltage and Speed Lockable Parameters”
With advanced microcontroller technology it is possible to lock the voltage and current parameters to desired level by the supervisor, ensuring complete run at desired WPS parameters without changes by the operators.
6.Weld Parameter Recording System”
Our data monitoring system can be easily added to this M/C to give complete log of welding parameters such as welding voltage, welding inverters & wire feed rate etc.
