AC/DC TIG Welding
AC/DC TIG welding combines both AC and DC pulses. The hybrid pulse mode is particularly effective for welding thicker aluminum materials. This method offers several advantages, including deep penetration without the need for preheating, extended electrode life, and precise weld bead formation, especially when using cold wire.
Standard Arc
Rectangular pulse shape, in which the peak value of both polarities is equal. The welding operations can be carried out in a wide range of sheet thicknesses. Since a stable welding result can be achieved over the entire current bandwidth, this is the most used waveform.
Hard Arc
Rectangular pulse shape in which the peak value of the polarities is different. Due to the concentrated arc in DC/TIG welding, the penetration depth increases. This makes this mode particularly suitable for fillet welds or the first layer in multilayer welding. Of the three modes, electrode wear is the lowest, but the arc noise is the loudest.
Soft – Silent Arc
Sinusoidal pulse shape in which the peak value of both polarities is equal. This produces a soft arc which is particularly suitable for thin sheets and butt welds. The arc sound is the quietest and the maximum welding current is 200A. The noise level is drastically reduced due to the sinusoidal current flow which realizes a controlled heat input.
