The DIGITIG 204 QUATTRO welding machine is the latest generation device, made in IGBT technology and equipped with digital control.

It is used for manual welding with the TIG DC method, MMA               a (a coated electrode) of steel and non-ferrous metals using direct current with the possibility of using current pulsations. It also enables plasma cutting of steel, aluminum and copper sheets and elements.

Digital control allows full adjustment and control of the welding parameters of the arc and pulse characteristics. Thanks to the use of the Fan Stop function, which turns off the fan at low load on the welding machine, the noise level has been significantly reduced.

In addition, it has HF ignition, the ability to control in two-stroke and four-stroke modes and a variant of spot welding, the so-called cold welding.

The welding machine is made in the IGBT inverter technology, which allowed for a significant reduction of its weight and dimensions. Stable output parameters guarantee obtaining high-quality weld.

Examples of applications: light industry, field repair work, workshop work, automotive, muffler welding.

IGBT TECHNOLOGY

Modern technology based on bipolar transistors with an insulated gate. It combines the ease of controlling field-effect transistors with the high breakdown voltage and speed of switching bipolar transistors. The use of the technology IGBT significantly extends the reliable operation of welding equipment.

PROTECTION LEVEL

IP determines the extent to which the device is resistant to solid and water contamination. IP23 means that the device is adapted to work indoors and is not suitable for use in the rain.

OVERHEAT PROTECTION

The IGBT module is protected against overheating by a protective installation that turns off the welding circuit of the device. After a few minutes, the welder cools down to a temperature allowing it to be automatically switched on again.

WORK CYCLE

The duty cycle is based on a 10-minute period. Duty cycle 60% means that after 6 minutes of operation of the device, a 4-minute break is required. 100% duty cycle means that the device can work continuously without interruptions.

MMA

A method that uses a covered electrode consisting of a metal core covered with a sheath. The device enables welding with all types of electrodes, e.g. basic, cellulose, rutile or acidic.

VRD

VRD function drops the no-load voltage. The correct voltage value is only restored just before the arc is struck. This minimizes the risk of electric shock, however, in some cases it may make it difficult to strike the arc.

TIG DC HF

In order to completely eliminate the possibility of contamination of the weld with tungsten, it is recommended that the electrode does not touch the workpiece; for this purpose, contactless arc ignition is used using high-frequency discharges generated by the ionizer built into the device.

HF - NON-CONTACT ARC STARTING

The device is equipped with an ionizer enabling contactless arc ignition.

WORKING MODE 2T / 4T

2T -  pressing the button in the handle of the handle turns on the ionizer and ignites the arc. Welding is carried out with the button pressed.

4T - pressing the button in the handle of the handle will turn on the ionizer and ignite the arc, then release the button and weld with the button released. Pressing the button again will stop welding

INITIAL CURRENT

The current appearing in the circuit after pressing the button in the handle of the handle. The higher the starting current, the easier it is to strike the arc.

However, when welding thin sheets, too high a starting current can lead to burn-in of the sheet. In some welding modes, the current does not increase to heat the workpiece.

RISE TIME

Rise time prcurrent  from the initial current to the set value of the welding current.

DOWNLOAD TIME

Current downslope time for welding from a set value to zero or crater current value.

GAS PREFLOW TIME

Time from pressing the button in the grip handle and opening the gas valve until the arc is ignited. Normally it should be longer than 0.5s to supply shielding gas to the torch nozzle outlet to shield the welding start and tungsten electrode.

GAS POST-FLOW TIME

Time from arc extinction to closing the gas valve to shield the solidifying weld pool from air and to cool the tungsten electrode. Too short post-flow time may result in oxidation of the weld. When welding in TIG AC mode (alternating current), this time should be longer.

TIG DC

Enables DC TIG welding. This is required for welding non-ferrous metals.

TIG PULSE

The function affects the shape of the weld and the arc focus. Pulse welding also allows you to reduce the amount of heat supplied to the material and is used when welding thin materials.

PULSE FREQUENCY

Frequency at which the value of the current pulse changes between the welding current and the base current.

PULSE WIDTH

Pulse duration, allows you to adjust the penetration depth. Increasing the width increases the depth of penetration, reducing the amount of heat introduced into the material, reducing the risk of burning through thinner sheets or smaller elements.

CRATER CURRENT

Current used in some welding modes when the arc is not extinguished immediately after the downslope phase of the welding current. Allows you to fill the crater at the end of the weld.

COLD TIG

Spot variant of TIG welding  – the so-called cold welding that allows joining thin elements, thanks to very low heat emission in the joining zone. It consists in cyclical short-term ignition and extinction of the arc.

• SPOT Pressing the switch in the handle of the handle will turn on the ionizer, ignite the arc for the time set by the COLD TIME parameter and extinguish the arc. Re-ignition of the arc requires releasing and pressing the button in the handle.

COLD TIME 0.01 - 2.5 seconds

Welding time during spot welding (cold welding).

PAUSE TIME 0.1 - 10s

Pause time during spot welding (cold welding). Only for CPOT control mode.

EASY TO USE, CLEAR CONTROL PANEL:

The easy-to-use control panel enables precise and smooth adjustment of parameters. Digital display indicates the actual current during welding.

PLASMA

Function for cutting electrically conductive elements made of carbon and alloy steel, aluminum and its alloys, brass, copper and cast iron

MAXIMUM CUT THICKNESS 12MM

The value of the maximum cut thickness was determined under optimal conditions for cutting ordinary quality carbon steel. In order to select the right device, it is recommended to perform technological tests in real working conditions and on an exemplary sample of the material.

STRONG AND SOLID CONSTRUCTION

The housing of the device is made of light and durablecomposites, resistant to all kinds of mechanical damage.

EASY TRANSPORT

Equipping the welding machine with a  transport handle  ensuring comfort when changing workplaces.

COOLING

The device has a cooling system fan which significantly increases its efficiency.
