WELDING INVERTERS - TIG

 
Sigma Weld SW400 : Welding Inverters From Electronics Devices
 
Sigma Weld series welding machines are sophisticated IGBT based inverters with total digital control having wide current range. Sigma Weld is designed to meet varied requirement of the welding industry covering Manual Arc Welding, TIG Welding, High Frequency TIG Welding, Pulse TIG Welding. Advanced micro controller technology enables Sigma Weld to have UpSlope / DownSlope and Pulsing even without the use of High Frequency.
 
Mobility: This 50 Kgs. inverter has 4 wheels so that the operator can move it easily from one location to another.
 
Low OCV: During energy saving, OCV goes down to as low as 20 VDC for added safety and energy saving.
 
Adaptive Hot Start: Sigma Weld prevents electrode from sticking and gives clean start each time.
 
Single Amperage Range : Digital front panel allows the operator to set the current is required in single increment also.
 
TIG Ignition - Lift-Arc : Sigma Weld provides TIG arc starting and there is no need to use of high frequency
 
In Built Gas Solenoid Valve : Operator can use very light TIG torch and use gas only as required, ensuring zero wastage of gas.
 
Thermal overload protection : Reliable thermal shutdown mechanism in place, in case of overuse or blockage in airflow.
 
Fan As Needed : Sigma Weld automatically operates the fan as needed, reducing the noise, power consumption and the airborne contaminants pulled through the machine.
 
Power Fluctuation Compensation : Power source does not get affected and it remains constant regardless of fluctuation in input power + 15%. It is suitable especially for the Indian Industry.
 
Digital Ampere Reading : During welding, it continuously monitors and displays weld current.
 
Robust : Sigma Weld can work with cable length of upto 50 m with reduced duty cycle.
 
Versatile : Sigma Weld can weld using all types of welding electrodes (suitable for 6010, 6013, 7018 and equivalent electrodes).
 
Process Memory Recall : It remembers separately the settings for each and every process. This leads to fast set up time between process changes and each Power ON.
 
Energy Saving Mode : When operator is not welding for 2 minutes, then welding inverter in Manual / Stick mode goes into energy save mode, enabling saving of unwanted energy loss.
 
AVAILABLE WELDING MODES
  • Stick (MMA)
  • Lift-Arc TIG (GTAW)
  • Lift-Arc/Up Slope/Down Slope
  • Lift-Arc/Up Slope/Down Slope/Pulsing
  • High Frequency/ Up Slope/Down Slope
  • High Frequency/Up Slope/Down Slope/Pulsing
MODELS AVAILABLE
 
MT : Manual/TIG inverter. SW400MT includes the basic features, which are necessary for DC TIG or Stick welding applications.
 
UD : Manual/TIG inverter. The SW400UD without HF starts with settable up slope and down slope timings along with Pulsing Control for Peak and Base Current, most suitable where high frequency is not permissible to use still can achieve the same control using only Lift Arc technology.
 
PW : Manual/TIG inverter. The SW400PW without HF starts with settable up slope and down slope timings along with Pulsing Control for Peak and Base Current, most suitable where high frequency is not permissible to use still can achieve the same control using only Lift Arc technology.
 
HF : Manual/TIG inverter with high frequency. The SW400HF provides HF starts with settable up slope and down slope timings where greater control is required.
 
PT : Manual/TIG inverter with high frequency pulsing control. The SW400PT provides HF starts with settable up slope and down slope timings along with Pulsing Control for Peak and Base Current where greater control is required.
