✅ Application

The DIGITIG 225GD AC/DC MIX welding machine is suitable for professional locksmith, production, service, automotive workshops and assembly works. Thanks to the AC, DC and MIX modes, the device is suitable for welding steel, stainless steel, aluminum and non-ferrous metal elements.

The device can be used both for precise welding of thin materials using the TIG method, as well as for repair or construction work using electrodes wrapped in MMA mode.

✅ Methods of welding

TIG HF – tungsten electrode welding in an inert gas shield with non-contact arc ignition using an ionizer. This solution reduces the risk of contamination of the tungsten electrode and the welded material, because the electrode does not have to touch the surface of the element.

TIG Lift – TIG welding with arc ignition by rubbing. This mode does not generate high-frequency pulses, so it is useful in environments sensitive to interference, e.g. near electronics, CNC controllers or in car workshops.

TIG MIX – mixed current welding, combining DC and AC direct current. This feature allows for a stable, concentrated arc, deeper melting, and effective surface cleaning. It works particularly well when welding aluminum and its alloys.

MMA – welding with a wrapped electrode. The mode is designed for assembly, repair and construction work, where versatility and the ability to work with different types of electrodes are important.

✅ AC/DC MIX function

The AC/DC MIX mode enables alternating use of direct and alternating current during TIG welding. Increasing the share of DC current allows for a more stable and concentrated arc, greater melting, narrower weld and better control over the welding lake. A greater proportion of AC current provides a wider arc, more effective surface cleaning and shallower melting.

MIX frequency adjustment allows you to adjust the nature of the arc work to the type of material and the expected quality of the weld. Higher frequency affects more stable arc, deeper penetration, narrower weld and reduced chipping.

✅ AC waveform adjustment

The device allows you to choose the waveform of the AC current, which allows you to adjust the arc characteristics to the type of material and thickness of the element.

• Rectangular wave – a universal waveform, most often used for welding various materials. It provides more heat in the welding zone and deeper melting.
• Sine wave – classic operating characteristics, similar to transformer welding machines. Suitable for users who prefer traditional arch operation.
• Triangular wave – recommended especially for thin materials, where it is important to limit the amount of heat introduced into the welded element.

✅ TIG Functions

• Pre Flow – a pre-outflow of gas before arcing, providing a shield for the tungsten electrode and the place where welding begins.
• Start Amps – initial current facilitating arcing and control of the beginning of the weld.
• Start Amps Time – duration of the initial current.
• Up Slope – the time of current build-up from the initial value to the welding current.
• Peak Amps – welding current or peak current when working with pulse.
• Peak On Time – pulse width, affecting the amount of heat and depth of melting.
• Base Amps – base current, i.e. the lower pulse value when welding with a pulse.
• Pulse Frequency – pulse frequency that regulates the transitions between peak and base current.
• AC Frequency – AC frequency, especially important for welding aluminium.
• AC Balance – AC balance regulating the ratio of positive and negative phases, affecting surface cleaning, weld width and melting depth.
• Down Slope – the time of current drop, allowing you to control the end of the weld.
• End Amps – crater current that allows filling the end of the weld.
• End Amps Time – duration of crater current.
• Post Flow – gas flow after arc extinction, protecting the cooling weld and tungsten electrode from oxidation.
• SPOT On Time – adjustable spot welding time.
• SPOT Interval Time – adjustable interval between spot welding cycles.

✅ MMA Functions

VRD – a function that reduces voltage in the unloaded state. Increases work safety by reducing the risk of electric shock. The full voltage value is restored immediately before the arc is ignited.

Hot Start – a hot start function that temporarily raises the current during arc ignition. It facilitates the start of welding and reduces the risk of sticking the electrode to the material.

Arc Force – arc dynamics adjustment. Increasing the value causes deeper melting and facilitates welding with a short arc, while lower settings give a softer arc and a smaller depth of melting.

✅ Handle operating modes

2T – two-bar mode. Welding is carried out with the handle button pressed. Release of the button completes the welding process.

4T – four-bar mode. After pressing and releasing the handle button, welding continues without having to hold the button. Pressing the button again begins the welding process.

SPOT – spot welding mode with adjustable welding time and intervals between subsequent points.

✅ Settings memory

The welder has memory of the last used parameters and the ability to save 10 complete sets of settings. This feature makes it easy to quickly return to proven configurations for specific materials, component thicknesses or repetitive welding jobs.

✅ Cooling and protection

The device is equipped with the Fan Stop function, which turns off the fan after welding and cooling the device. The fan restarts under load. This solution reduces noise, reduces dust suction inside the welding machine and improves work comfort.

The welder also has thermal protection. In case of overheating, the device automatically disconnects the welding current, the O.C. light turns on, and the “Err” message appears on the display. When the temperature is lowered, the protection resets automatically.
