This is a microprocessor based optimized design along with added features like adaptive hot start, arc force control, helps achieve seamless beads with all steels and alloy steels,. Welding with all types of electrodes such as 6013, 7018, SS316, SS308 or 6010 is also possible with ease.
The output of sigmaweld welding inverters are constant even if there is a power fluctuation int he mains of up to +-15 %. The power source equally works well on generator sets with balanced load. The output current does not even drop at 100 meters of copper cable length
Energy Saving, VRD InbuiltWhen the operator is not welding for more than 2 minutes, the power source automatically switches to low OCV output below 24V for safety of operator. This also leads to saving of no load losses.
The optimized design along with added features like Adaptive Hot Start, Arc Force Control, helps achieve seamless beads with all streels and alloy steels. welding with all types of electrodes such as 6013, 7018, SS308, or 6010 is also possible with ease.
Sigma Weld 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
