The Ampero 225 ALU welding machine from the Welbach brand facilitates the use of different welding methods. Welding current of 10 - 225A can be either for TIG use or MMA welding, depending on the metal to be welded and the conditions under which it is to be welded. Even for the welding of thin metal sheets, this welding machine is ideally suited.
The Ampero 225 as a TIG welder welds almost all melting metal grades and their alloys such as aluminium, copper, nickel or steel. This machine can be used in a variety of positions, be it overhead or vertically. The produced welding seams need little, if any reworking.
The MMA welding method of the Ampero 225 requires no gas, which means that the device can be used even under adverse conditions such as outdoors and still achieve clean welding results with an electrode. In the case of MMA welding, the device is suitable for iron or steel as well as alloys such as cast iron, aluminium or copper. The welding machine impresses with a very stable welding current, which helps facilitate high-quality welding seams.
The digital control panel is very clear and easily readable. The required parameters can be simply selected there and the corresponding value can be set via a knob control. The memory function saves the last selected settings for the following welding work. Auto-mode can also be used for welding, but also to pre-set parameters.
For example, the pulse function on the control panel can be simply activated for TIG welding. Among other things, it enables precise welding of thin sheet metal. Different parameters such as pulse rate and base current can be selected and adjusted using the knob control. However, other typical TIG welding functions such as the option of either an AC or DC current.
The welding current is first set on the control panel for manual use, however for optimal welding results some functions are activated automatically. With HOT START the ignition of the arc is facilitated with a briefly increased voltage. ARC FORCE increases the voltage once the arc becomes shorter, and ANTISTICK prevents the overheating of the electrode, preventing the electrode from sticking to the weld, by switching off the welding current.
The AC / DC welding machine Ampero 225 requires a supply voltage of 230 V and operates with a modern IGBT bipolar transistor. The device can also be conveniently operated with a foot pedal, which can be purchased separately. The supplied cables for both the TIG and MMA torch are both four meters long, as so is the ground cable, therefore sufficient freedom of movement during the welding process is provided.
IGBT = insulated-gate bipolar transistor. IGBT is a bipolar transistor with an insulated gate electrode. This semi-conducting device is being increasingly used in power electronics because it combines the advantages of two transistor types: the easy controls of the field effect transistor and the fast switching and high breakdown voltage of the bipolar transistor. The IGBT also offers some robustness against short circuits because it limits the electrical continuity. IGBTs are a further development of MOSFET technology.
Powerful fans ensure an optimal removal of heat from the unit.
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.
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.
This unit can also be operated using a foot pedal.
This device works with a 1-phase connection (230 V +/- 10 %).
A non-contact high-frequency ignition in TIG mode ensures a cleaner weld starting point.
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.
Value of the arc ignition output current. This current can be adjusted at will. For precision welding, it is recommended to start with reduced power, weld smoothly and eventually adjust the current accordingly.
The time taken by the output power to rise to that of the welding current’s value.
The time taken of the output welding current to lower to that of the terminal current.
The output current value before the end of the weld. Welding with the final current helps prevent a crater forming at the end of the weld.
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.
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.
The frequency of impulses during pulse mode.
Relation of pulse duration to period duration.
The maximum value of the electric current while in pulse mode.
The current which maintains the arc while in pulse mode.
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.
This is the percentage difference between the positive and negative welding current value during a period.
Start the weld by placing pressure on the torch button. Stop the process by releasing the button.
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.
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.
The current value increases automatically when the arc is shorter.
This function helps to prevent overheating of the electrode by switching off the welding current when the electrode sticks to the material.
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.
Electrode welding with a coated electrode.
Choose between the 2T and 4T mode.
TIG welding is divided into AC (alternating current) and DC (direct current) welding.
Used to switch the pulse function on and off.
By using the SHIFT key the welding mode can be selected.
Choose between either “MANUAL" control, to manually input the parameters or "SYNERGIC/EASY", in which the device will set parameters partially by itself.
