The TIG welder S-ALU 225PH's control panel is clearly arranged and is easy to use while wearing welding gloves. Four toggle switches allow you to directly choose the basic welding functions (TIG, MMA, AC, DC, 2T, 4T, Pulse). The required values for the individual welding functions can then be set by means of nine infinitely variable rotary controls. The LED display lets you keep an eye on the current amperage.

The welding machine has a maximum power of 225 amperes with a duty cycle of 60 percent. If the power is reduced to 174 amperes, you can weld without interruption. With its high performance, the welder can even weld thicker metals up to 9 mm quickly and precisely.

The TIG DC welding method can be used for welding more robust metals such as steel, stainless steel, copper or brass. The torch produces few sparks and spatter and guarantees pure, high quality welds that leave very little distortion. In addition, you can use the welder in various positions, whether vertical, horizontal or overhead.

This welder gives you the option of welding with either AC or DC TIG, so you can work with either direct or alternating current, depending on the metal. Alternating current (AC) is suited for light metals such as aluminium or titanium. Direct current (DC) can be used for welding more robust metals such as steel, stainless steel, copper or brass.

The Pulse function is particularly useful for welding thin sheets from 1 millimetre—especially those made of aluminium. Even under difficult conditions, the arc can be easily stabilised since the pulse frequency is adjustable up to 300 Hz. It is also possible to select numerous parameters such as start or end current for pulsed current welding, and to optimally adjust them to the workpiece with the aid of the control knob. You can adjust the pulse frequency between 0,5 and 300 Hz for stable welding results and a better cleaning effect when welding at a high frequency, for example with anodise aluminium sheets.

The welder uses proven MOSFET inverter technology, which has an efficiency of 93% and guarantees a stable welding current. The result: Perfect welds. The welding arc is activated via reliable high-frequency ignition (HF).

No additional gas is required for MMA (Manual Metal Arc) welding, enabling it to be used outdoors even in strong wind. With this welding method, the welder generates a very stable current, all the while securely maintaining the voltage. This allows you to make high-quality welds on a wide variety of metals.

The MMA welding clamps can grasp even large electrodes with a diameter of up to 4 mm. With the MMA welding method, you can weld materials such as steel, iron, cast iron, nickel or copper from 1,5 to 9 mm thick. The welding machine enables you to correctly install and maintain railings, stairs, gates, doors, containers or metal machinery.

The electrode welder's hot start function ensures an automatic and short-term increase of the welding current at the start of the welding process. Thanks to this “hot start”, the starting point is immediately heated to the optimal temperature and the electrodes do not clog. This creates a clean, stable weld from the very first moment.

The ARC Force function regulates the arc sensor and adapts it to the perfect density for the respective material. You can select the ampere strength for ARC Force using the digital control panel.

MOSFET

The welder is equipped with a MOSFET transistor. This technology represents the highest standards of performance combined with compact and lightweight design. The result is 93% efficiency! The welding current is very stable and thus ensures a perfect weld.

VENTILATORS

Powerful fans ensure an optimal removal of heat from the unit.

PROTECTIVE GAS

TIG/MIG and MAG welding require a protective gas. Inert gases, such as argon and helium, as well as active gases (for example carbon dioxide) and other mixtures can be used. The solenoid valve regulates the flow of gas. The valve is operated via a button on the torch.

EARTHING SYSTEM

On the back of every welding machine is a screw with an earthing mark. Before use, earth the unit via a cross-section cable, which must be at least 6 mm².

GROUND TERMINAL CONNECTOR

MMA WELDING CABLE CONNECTOR

TIG TORCH CONNECTOR

FOOT PEDAL CONNECTOR

This unit can also be operated using a foot pedal.

SUPPLY VOLTAGE

This device works with a 1-phase connection (230 V +/- 10 %).

NON-CONTACT HF-IGNITION

A non-contact high-frequency ignition in TIG mode ensures a cleaner weld starting point.

GAS PRE-FLOW TIME

This is the time taken from the moment of pressing the torch button to that of the electric arc igniting. During this process the solenoid valve opens and the released gas pushes the oxygen from the gas lines and in doing so, forms a protective atmosphere for the arc.

WELDING CURRENT

DOWN SLOPE TIME

The time taken of the output welding current to lower to that of the terminal current.

GAS POST-FLOW TIME

The time after the weld is finished in which gas continues to flow from the torch; this cools the burner and protects the weld from oxidation.

PULSE

This function reduces the heat to the material. It is primarily suitable for welding thin plates. If MIG welding is used, it is perfect for aluminium welding.

PULSE FREQUENCY

The frequency of impulses during pulse mode.

IMPULSE CURRENT

The maximum value of the electric current while in pulse mode.

BASE CURRENT

The current which maintains the arc while in pulse mode.

POWER FACTOR CORRECTION

This is the percentage difference of the time between the positive and negative direction of the current during a welding period. This feature allows control of the width of the welding seam and the depth of penetration.

CLEAN WIDTH - PARAMETERS OF POWER FACTOR CORRECTION

This is the percentage difference of the time between the positive and negative direction of the current during a welding period.

2-STROKE

Start the weld by placing pressure on the torch button. Stop the process by releasing the button.

4-STROKE

By pressing the torch button the solenoid valve opens. allowing the gas to flow in. The gas pre-flow ignites the arc at the pre-set current. Releasing the burner button initiates a rise in the current to that of the pre-set welding current. The welding process stops once you press the burner button again.

HOT START

Through automatically boosting the tension at the ignition of the arc, this function facilitates the electrical arc ignition. After ignition, the unit automatically returns to the pre-set voltage.

Show moreShow less

ARC FORCE

The current value increases automatically when the arc is shorter.

ANTI-STICK

This function helps to prevent overheating of the electrode by switching off the welding current when the electrode sticks to the material.

TIG WELDING

A welding method in which the arc is maintained through an electrical current supplied from a non-consumable electrode. The arc is protected from the access of air by an inert gas.

MMA WELDING

Electrode welding with a coated electrode.

POWER SWITCH

"2T / 4T" SELECTION SWITCH

Choose between the 2T and 4T mode.

TIG AC/DC MODE SWITCH

TIG welding is divided into AC (alternating current) and DC (direct current) welding.

PULSE FUNCTION SWITCH

Used to switch the pulse function on and off.

SWITCH BETWEEN THE WELDING METHODS

By using the SHIFT key the welding / cutting mode can be selected.

DISPLAY

OVERLOAD / FAULT LED

The LED light indicates overheating or a malfunction.

Do I have to prepare the workpiece for welding? And if so, how?

Chemical and flammable substances must be removed from the surface before welding as they can catch fire and release toxic substances.

How can I be sure that the accessories that are delivered with the welder are compatible?

When selecting the accessories, expondo places a strong emphasis on making sure that all components work perfectly together so that you can ensure the best possible welding results.
