AC Welding Controller TNS-815 V2

• Simple Operation

• Multiple Heats & Pulsation

• Single & Dual Gun Operation

• Built On Spot & Job counter




With the help of Large Display panel Set Parameters and Monitored Data can be continuously viewed which helps operator manage the welding process.


Error Display

Error number will be displayed on the Display panel along with error alarm. Description of the error is mentioned on the face plate which helps operator resolve the problem instantly.


Combination of constant current and voltage compensation

To achieve high quality weld in Zinc coated sheets.

Combination of constant current and voltage compensation is available. Multiple heats and pulsation are also available.


Suitable for spot & Projection Built-in Spot & Job counter

2 separate Displays for Spot & Job count, this helps to monitor production quantity at any given time.
