Product Overview

  • The Multipower 204T is a highly sophisticated TIG DC or MMA Inverter, with simple operator interface, with dual voltage capability for use on either 240v or 110v. In TIG DC mode materials such as carbon steel, stainless steels and copper can be easily welded. The multipower 204T is suitable for high precision welding in environments such as petrochemical plants, food industry and many more that require high performance. Multipower 204T  series also introduces new technological solutions in order to reduce the harmonic current emissions according to the future International standards, this is designed to increase even more the power inverter efficiency of the machine, and reduce the input current by more than 20%. The same welding deposit is achieved with less electrical power, less total power and less CO2 emission.


     Features:

    Multipower204T is equipped with a PFC (Power Factor Corrector) dimensioned to support a supply voltage from 90Vac up to 270Vac, with an "intelligent" system capable of delivering all available power output depending on the working condition.The PFC function makes it usable on generators and with power cables of more than 100 meters in length.

    Weco Special HF control gives 100% rapid and precise striking.

    The DYNAMIC ARC function allows an increase of the welding current when the arc voltage decreases and vice verse (the power source reduces the welding current if the arc voltage increases). The Dynamic Arc value                    can be adjusted from a minimum of 10 amps to a maximum of 50 amps with each variation of 1 Volt, whether this is positive or negative. This value should be set in accordance with the thickness of the base material, and the type of processing that has to be carried out, a value between 1amps and 20amps is recommended for thin gauge material, and values between 20amps and 50amps for thicker gauge. The Dynamic Arc function also permits the welding with extremely short arcs, when the electrode is extremely close to the base material, the current increases and avoids the contact of the electrode, by shifting of the welding pool. This prevents both the electrode’s sticking to the material and the inclusion of tungsten’s particles into the weld deposits. Despite the arc length variations the energy absorption remains constant throughout the welding process.

    The Q-START (Quick Start) function makes it possible to minimizes tacking time. A series of adjustable pulses, creates a movement of molten material between the two edges of the material being joined in order to accelerate the joint. This function is invaluable in the case of seams with slight openings or with irregular preparation. The alternation of high and low current pulses, constantly changes the electric arc geometry from wide to narrow. This stimulates movement of the molten material, which follows the arc geometry, it is such that the two molten edges are rapidly brought into contact. The duration of the series of pulses can be adjusted, from 0.1 to 10seconds depending on the thickness and shape of the material being joined.Q-START also offers a more rapid start of the welding process, when it is used for tacking, it is also possible to obtain very clear tack without the normal oxidation stains.

    The MULTITACK function makes it possible to minimize the heat output when joining two thinner gauge parts. The series of repeated arc strikes at short time pre-set intervals allows the material to cool during the pause, and between one strike and the next. The Adjusting of the arc strikes’ frequency in the timer unit, makes it possible the optimizing both the welding penetration and execution speed, above all the heat output remains totally under control, drastically reducing the possibility of work piece deformation.When fillet welding it is possible with the use of Multitack, to achieve excellent results. The weld remains white and without any surface discolouration or oxidation, thus reducing the need for acid treatments which often must be applied post welding.

    The new Q SPOT function greatly facilitates the spot welding process: It allows precise positioning of the electrode in the point to be joined at the closest possible distance. The electrode is conveniently placed on the fixing point so the operator can perfectly control the entire cycle. Once the electrode is lifted the machine emits a welding current pulse with a present time. This means that the sheet metal edges are instantly joined with the minimum heat transfer. The risk of contamination of the joint and the electrode falls significantly.1. Positioning of the torch with the electrode on the work piece.2. Press the torch trigger and keep it pressed.3. Lift the torch slightly. As soon as the electrode is lifted then the HF ignition starts.4. The arc ignites for few hundredths of a second, the duration can be altered on the timer set up.5. The result of this is a very precise, not oxidized welding spot, without any deformation of the sheet.

    TIG DC standard functions include Pre Gas, Post Gas, Up Slope, Down Slope, Start Current, and Final Current.

    A wide range of adjustable pulse frequencies together with extra parameter controls (Base Current and Duty Cycle) allows operating in slow pulse and fast pulse.Fast Pulse TIG DC gives a focused arc for optimum performance when welding thinner material, offering lower deformations. Slow pulse TIG DC  is recommended for thicker plate and welding with TIG filler rods. Pre-set balanced parameters are also stored in a Synergic Pulse TIG DC Curve, simplify pulsed welding by adjusting only the welding current.

    Trigger control settings include 2T/4T/Bi-Level and Spot Welding.

    The VRD function (Volt Reduction Device) reduces the value of open-circuit voltage of the machine during the standby mode, to allow for work to be carried out in environments where safety requires working voltages limited, such has shipyards, oil platforms, etc.

    MULTIPOWER 204T also allows the selection of the type of coated electrode to be used, so that the machines suitable parameters fixed and dynamic, give the optimised parameters for the material being welded.

    With 50 program memory, applications produced on a regular basis can be programed and recalled when required to reduce set up times.

    Adjustable Hot Start, Arc Force and automatic Anti Sticking facilitates operations with up to 3.25mm diameter electrodes when MMA welding.

    Fan on demand and Built-in Wind Tunnel protects electronic devices from dust and saltiness and improves reliability

    Handle and Shoulder Strap for easy carrying are also supplied with the machine.
