WELDINGER WE 250P AC/DC digital pro TIG welding inverter for aluminum 250 A

WELDINGER WE 250P AC/DC digital pro TIG welding inverter for aluminum 250 A

Professional digital welding machine of the latest generation for aluminum welding

Versatile use for steel, stainless steel, aluminium, cast iron, copper, bronze, magnesium and galvanized material

The WELDINGER WE 250P ACDC is a digital TIG welding inverter for DC and AC welding. All TIG functions can be controlled and saved via the clearly laid out digital display using modern one-button operation. An integrated parameter diagram provides information at a glance about the selected settings and the status of the welding process.

In contrast to simpler TIG devices, the WE 250P ACDC allows precise fine adjustment of all relevant values in order to achieve the best results with the respective material. In TIG and MMA mode, 10 welding jobs can be saved in each mode, which significantly shortens work with frequently used material because the settings only have to be made once.

Adjustable in TIG mode:

GAS PREFLOW The gas pre-flow time is the time between pressing the torch trigger and opening the gas valve until the arc is formed. Under normal conditions, the value should be above 0.5 s. The setting range is between 0 and 10 s.

HOT START ensures better ignition behavior by briefly increasing the welding current (adjustable from 20-250 A).
START CURRENT The start current starts after the burner button is pressed. The higher the starting current, the easier the arc is formed. The setting range is between 20-250 A.
RISE TIME The rise time from the starting current to the welding current. The setting range is between 0-20 s.
WELDING CURRENT The welding current setting range is between 20-250 A.

BASE CURRENT The base current makes it easier to control the heat that is introduced into the material. The base current can only be set during pulse welding. The setting range is between 20-250 A.
SPOT WELDING (s) Setting the welding time in spot welding mode. The setting range is between 0-10 s.
PULSE WIDTH Here you set the duration of the pulse to influence the depth of the burn-in. While a higher value ensures deeper firing, a lower value means less heat is introduced into the material. This reduces the risk of burning through thinner sheets or small parts during welding. The setting range is between 10-90%.

PULSE FREQUENCY This is the frequency at which the pulse value varies between the welding current and the base current. The setting range is between 0.1-20 Hz.
AC FREQUENCY This function is required for aluminum welding. The higher the frequency, the better the welding quality and the concentration of the arc. The adjustment range is between 20-200 Hz.
AC BALANCE This controls the ratio of the duration between the positive and negative phases.

If you reduce the balance value, you introduce more heat into the material, create a narrower seam and a deeper penetration. At the same time, you reduce the heat load on the tungsten electrode. By increasing the value, you apply less heat to the material and achieve a wider seam with less penetration. The load on the electrode is higher. The adjustment range is between 10-50%.

ARC WIDTH Used to control the arc spread in AC mode. Adjustable from -50 to +50%.
DESCENT TIME The descent time from the welding current to the final current. The setting range is between 0-10 s.
FINAL CURRENT Here you set the final current for the final crater filling. The setting range of the closing current is between 20 A-250 A.
GAS AFTERFLOW The gas afterflow time is the time from when the arc cools down until the gas valve closes. While gas flows in, it protects the solidifying molten bath from oxidation and cools the tungsten electrode. If the post-flow time is too short, this can result in oxidation of the weld seam. The setting range is between 0 and 10 s.

In TIG mode, you also have the option of choosing between normal and pulsed mode, as well as between 2T, 4T, S4T and spot welding mode. A particular highlight is the variability of the wave mode for influencing the arc with thin materials.

Manual electric welding
The WE 250P ACDC also achieves professional results when electrode welding and can weld stick electrodes with a diameter of 1.6-5 mm. A suitable electrode holder cable is available separately in our store (e.g. article 2003).

The WELDINGER WE 250P ACDC is the ideal welding machine for advanced users. In our store you will find an extensive range of spare and wear parts, as well as tungsten electrodes and TIG welding rods for every conceivable application. If you do a lot of TIG welding and have to grind your tungsten needles frequently, we recommend the WELDINGER TIG grinding boy (item 3726) for optimum grinding. If you prefer to work with a bench grinder, we offer the WELDINGER TIG grinding aid (item 4774), an excellent holder that makes the grinding process much easier.
