DIGIMIG 351 Synergic Welder COMBO LCD is used for welding steel and non-ferrous metals and brazing thin galvanized sheets. It allows welding using MMA, TIG Lift, and MIG methods. The MIG method can be used in manual mode and with the use of synergistic programs.

Thanks to the change of polarity, the device allows for MIG welding using both standard wires in a shielding gas and self-shielding flux-cored wires.

Using pulse or double pulse allows for better weld quality, high aesthetics and very high efficiency.

Digital control, a very large (7”) color LCD display, an intuitive menu and synergistic settings for carbon steel and aluminum alloys used in the welder significantly simplify its operation.

During MMA welding, the HOT functions can be adjusted START, ARC FORCE and disable VRD. The welding torch hanger helps maintain order and increases work safety.

Thanks to the Fan Stop function that turns off the fan at low welding load, the noise level has been significantly reduced.

IGBT TECHNOLOGY

Modern technology based on transinsulated gate bipolar resistors. It combines the ease of control of field effect transistors with the high breakdown voltage and switching speed of bipolar transistors. The use of IGBT technology significantly extends the reliable operation of welding devices.

PROTECTION RATING

IP rating determines the degree to which the device is resistant to the ingress of solid and water contaminants. IP21S means that the device is suitable for use in enclosed spaces.

MMA

A method that uses a coated electrode, consisting of a metal core covered with a coating. The welder feeds the electrode as it melts into the workpiece so as to maintain a constant arc length. The device allows welding with all types of electrodes, e.g. basic, cellulosic, rutile or acidic.

VRD

VRD function (Voltage Reduction Device – a module reducing the rest voltage (idle) of the device's secondary circuit) available in MMA mode. Increases safety and reduces the risk of electric shock.

ARC FORCE

A function that stabilizes the arc by maintaining the welding arc voltage value regardless of its length and makes it easier to control the amount of spatter.

HOT START

When the arc is struck, the welding current is temporarily increased to heat the material and electrode at the point of contact and to properly shape the penetration and weld face in the initial phase of welding

OVERHEATING PROTECTION

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

MIG/MAG

Gas-shielded arc welding is one of the most commonly used processes for manufacturing welded structures.

GASLESS WELDING

Thanks to the polarity change function, it is possible to weld without a shielding gas, using a self-shielded FCAW wire. This is a method using self-shielded flux-cored wire for welding (in all positions) normal and high-strength steel not exceeding 510 MPa.

INDUCTIVITY CONTROL

Allows optimization of arc characteristics depending on the thickness of the welded element and the welding method and conditions. This function is useful when welding thin elements using the MIG/MAG method, preventing them from burning through, and brazing galvanized elements.

DUTY CYCLE

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

SYNERGY

MIG/MAG welding using synergistic settings. The device selects welding parameters depending on the selected type and thickness of material. These parameters can be changed by the user to adjust the settings to their own needs.

TIG DC LIFT

Tungsten electrode welding in an inert gas shield. This method allows welding of all types of steel, i.e. carbon, alloy, stainless, acid-resistant, as well as copper alloys, e.g. bronze or brass.

2T/4T

2T - Pressing the welding torch button will cause gas pre-flow, then ignite the arc and start welding. After releasing the button, the arc will extinguish and the gas will post-flow.

4T - Pressing and releasing the welding torch button will cause gas pre-flow, then ignite the arc and start welding. Pressing and releasing the button again will extinguish the arc and stop the gas flow.

EURO CONNECTOR

Standard welding torch connection, which allows for the connection of various types of torches (e.g. prepared for welding Aluminum by replacing the Teflon insert and contact tip).

SPOOL GUN

Possibility of using a SPOOL GUN torch with a built-in wire feeder (torch not included in the set). The method allows welding both in a gas shield and with a self-shielded wire without gas.

MIG PULSE

An advanced form of welding that uses the best of the forms of transfer of molten electrode material to the welded object. Unlike short circuits, pulse welding does not produce spatter or the risk of cold "drip".

By cooling the spray arc process, pulsed MIG is able to extend the welding range, and the lower heat input does not cause a problem with burning through thin materials. MIG PULSE is one of the best welding processes for a wide range of applications and metal types.

MIG DOUBLE PULS

The MIG/MAG double pulse method allows you to adjust the current pulsation (pulse balance) and adjust the wire feed speed. This improves the appearance of the weld. When welding with the MIG/MAG double pulse method, current pulses occur in two ranges.

PULSE WIDTH

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

PULSE CYCLE

The frequency with which the current pulse value changes between the welding current and the base current.

PRE GAS

Adjusts the shielding gas flow time before welding.

POST GAS

Adjustment of shielding gas flow time after welding.

4 ROLLER WIRE FEEDER

Professional wire feeder, has a powerful motor that allows for stable wire feeding without jamming. It is equipped with 4 drive rollers.

STRONG AND SOLID CONSTRUCTION

The device housing is made of light and durable composites, resistant to all types of mechanical damage.

EASY TRANSPORT

The welder's transport chassis ensures convenience when changing workplaces.

COOLING

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