Key Features of Manual/TIG Inverter with High Frequency and In-Built Digital Ammeter

• Portable: It is very portable at 12 Kgs. [basic inverter] operator can move from one place to another place without any difficulty.
• 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.
• Rated Input Voltage: 1-phase 230V + 10% 50/60 Hz
• Rated Power [KVA] at 100%: 5. 1 KVA
• Rated Current Duty Cycle: 70% at 170 A / 100% at 130 A
• OCV-DC: 80 V [nominal], 20 V [energy saving mode]
• Energy Save: In built
