In the AC TIG mode, the following wave forms are available: square wave, soft square wave, and triangular wave. The Invertig 400 offers the ability to run on single-phase power, from 208 to 240V, or on 3-phase power, from 200 to 575V. We designed the Invertig 313 to run on single-phase or 3-phase power, from 208 to 240V only!

All wave forms are available in AC TIG and Stick welding mode. Pulse can only be used with square wave.
Square Wave: The standard wave form for all modern inverter TIG welding machines. The square wave offers excellent power, arc control, and bead appearance. A good choice, all around, for aluminum welding. When in use, some operators may perceive the square wave sound as loud and unpleasant. However, many operators prefer to use a square wave due to its superior performance and features, such as the ability to run pulse.
When Soft AC and Triangular AC are turned off (Fig. 4), the machine is in square wave.
Soft Square Wave: The soft square wave provides a more sinus like wave form, which allows for a softer arc and a more fluid weld puddle, and it does so while creating significantly less noise. The SOFT symbol on the right-hand side of the LCD above the 3-phase symbol (Fig. 5) indicates that Soft AC is selected and active. Also referred to as a modified square wave. Pulse functions are unavailable in Soft AC.
Triangular Wave: The triangular wave form allows you to reach maximum peak current while dramatically reducing the overall heat input. When using a triangular wave form, the machine can be configured to show either the maximum (peak) amperage or the overall (actual) amperage welding output on the LCD. The Amperage display (red numeric; above LCD) always shows the max (nominal/peak) amperage. Rapid formation of melting points reduces the overall welding time, which, in turn, alleviates distortion-especially when welding thin material. The triangular wave creates a fast freezing puddle, which results in superior control and heat input management. When in use, the triangular wave function symbol appears on the main screen of the LCD. The TRI symbol on the right-hand side of the LCD above the 3-phase symbol (Fig. 6) indicates that Triangular AC is selected and active. Pulse functions are unavailable in Triangular AC.
