Adjustable parameters:
| Parameter | Value | Description |
|---|---|---|
| Current mode | DC- / DC+ / AC / MIX | DC TIG: Direct current TIG welding process, where the polarity of the electrode is either positive or negative throughout the welding process. Negative polarity (DC-) allows high penetration, whereas positive polarity (DC+) is used only in special applications. AC TIG: Alternating current TIG welding process, where the polarity of the electrode alternates rapidly between positive and negative. Used especially in aluminum welding. MIX TIG: TIG welding function, where AC TIG and DC TIG processes alternate in predefined manner. Parameters are preset by the user according to welding application. Used especially for optimizing welding of aluminum materials of dissimilar thicknesses. |
| AC Waveform | Sine / Optima / Square (Default: Optima) | Function to change the wave form of the alternating current in AC TIG welding. Three options are available: sine, square and Optima. The wave form affects the shape of weld bead, penetration of the weld and the noise of the welding process. Select the one that suits the application. |
| AC Frequency | 30 Hz ... 250 Hz (Default = 60 Hz) | Function to change the frequency of the alternating current in AC TIG welding. This setting adjusts the number of cycles per second. Used for changing the frequency of the welding current to best match the welder's preference and application. |
| AC+ / AC- balance | Min/Max = -60 % ... 0 % (Default = -25%) | Function to adjust the positive and negative current cycles in AC TIG welding. Low percentage means that, on average, the welding current is more on the negative side, and high percentage that, on average, the welding current is more on the positive side. |
| MIX TIG AC (time) ratio | Min/Max = 10 % ... 90 %, step 1 % (Default = 50 %) | MIX TIG: TIG welding function, where AC TIG and DC TIG processes alternate in predefined manner. Parameters are preset by the user according to welding application. Used especially for optimizing welding of aluminum materials of dissimilar thicknesses. |
| MIX TIG cycle time | Min/Max = 0.1 s ... 1.0 s, step 0.1 s (Default = 0.6 s) | |
| MIX TIG DC level | Min/Max = 50 % ... 150 %, step 1 % (Default = 100 %) |
