Conventional and triangular-wave TIG welding - MEGMEET MetaTIG ACDC HF TIG Welders 315A

Square Wave DC/AC square wave, polarity fast-switching, high stability of arc, good dynamic characteristics, strong ability to clean aluminum oxide film, suitable for a wide range of aluminum and aluminum alloy welding.	Sine Wave DC/AC sine wave, rectangular transition at zero-crossing point, less and softer arc noise.
Triangle Wave Short peak-time and low heat input, suited to welding of thermo-sensitive metals as thin plates.	Trapezoidal Wave DC/AC trapezoidal wave, polarity stable-switching, and soft arc bring a good wetting effect to the fusion pool, applicable for groove welding and overhead welding.

3. 0.1Hz-3000Hz High-Frequency Output - Enable high-quality welding from extreme-thin to medium-thin plates

5. AC-DC Pulse

DC is blended into AC-wave to further raise the heat input of base metal and increase the depth of penetration;
In AC-DC Pulse, tungsten rod loss could be reduced in DCEN;
In AC-DC Pulse, the EP ratio is adjustable in the AC section to improve the cleaning effect;
Arc stiffness and concentration are good and heat input is high to further improve welding efficiency.

10. MetaTIG ACDC Series is capable to weld diversified metals.

Carbon Steel	Stainless Steel	Aluminum Alloy	Copper
Output current ripple is small and arc is stable. Fusion pool is well controllable.	High-frequency pulse effectively compresses arc and reduces heat-input, easier welding for thin-plate stainless steel and welding shape is more beautiful.	Variable polarity to adjust the range ratio of EN and EP, combined with the cleaning width, brings high-quality welding for aluminum alloy welding.	With unique triangular wave, sine wave, square wave, trapezoidal wave, complex wave and other waveforms, welding for copper, titanium, magnesium and other troublesome metals is easier.
