FUNCTIONS

2T - Pressing the welding gun button will cause pre-gas flow, then arc ignition and welding. After releasing the button, the arc will be extinguished and gas will flow out.

4T - Pressing and releasing the welding gun button will cause gas pre-flow, then arc ignition and welding. After pressing and releasing the button again, the arc will be extinguished and gas will flow out.

S2T - Pressing the welding gun button will cause pre-gas flow, then arc ignition and start of HotI welding current. After the HOTt time has elapsed, the welding current will change to the set value. Releasing the torch button will change the welding current to EndI, and after the Endt time the arc will be extinguished and gas will flow.

S4T - Pressing the welding gun button will cause gas pre-flow, then arc ignition and welding start with HotI current. Releasing the button will change the welding current to the set value. Pressing the torch button again will change the welding current to EndI, and when the button is released, arc quenching and gas leakage will occur.

SPOT - Spot welding. Pressing the welding gun button will cause gas to escape and the arc to ignite. After the Sppt time has elapsed, the arc will be extinguished and the gas will leak. An earlier release of the handle button will immediately extinguish the arc and cause a gas leak.

CPOT - Continuous spot welding. Pressing the welding gun button will cause gas to escape and the arc to ignite. After the Sptt time expires, the arc will be extinguished. After the Stop time has elapsed, the arc will ignite again and the cycle will continue until the handle button is released, then the arc will extinguish and gas flow.

WELDING SELECTION BUTTON [H]

SYN MIG - MIG / MAG welding using synergic settings. The device selects welding parameters depending on the selected type and thickness of the material. These parameters can be changed by the user.

PULSE - MIG / MAG welding with pulse. This is an advanced form of welding using the best form of transfer of molten electrode wire material to the welded material. Significantly reduces the formation of chips and allows welding in all positions. Smaller heat input eliminates burning of thin materials. This method uses synergic settings.

D-PULSE - MIG / MAG welding with double pulse. This is the most advanced welding method in which current pulses occur in two ranges. It combines the benefits of welding with a single pulse, and also allows you to get a very high aesthetics of the weld face - the so-called scale effect. Welding with this method is very efficient, causes small deformations and at the same time allows you to get a perfect weld appearance. This method uses synergic settings

SPL MIG - MIG welding with manual selection of settings

PULSE TIG - TIG lift welding with pulse

LIFT TIG - TIG lift welding.

PULSE MMA - MMA welding (coated electrode) with pulse

MMA - MMA welding (coated electrode).

MMA METHOD and PULSE MMA

The VRD function reduces the voltage in no-load condition. The correct voltage value is not restored until just before the arc strikes. This minimizes the risk of electric shock, however, in some cases it can hinder the ignition of an arc.

The ARC FORCE function allows you to adjust the dynamics of the welding arc. The shortening of the arc length is accompanied by an increase in the welding current, which stabilizes the arc. Decreasing the value gives a soft arc and a smaller penetration depth, while increasing the value causes deeper penetration and the possibility of short arc welding. When the ARC FORCE function is set to high, you can weld while maintaining an arc with a minimum length and high electrode melting speed.

The HOT START function is popularly called hot start. It works when the arc ignites, temporarily increasing the welding current above the value set by the welder. HOT START is aimed at preventing the electrode from sticking to the material and is a great help during ignition of the arc. When welding small parts, it is recommended to disable this function, as it may cause burnout.

SYN MIG, PULSE, D-PULSE and SPL MIG METHODS

During MIG welding, the device can operate in synergic (SYN MIG, PULSE, DPULSE) and manual (SPL MIG) modes.

The synergic mode allows welding parameters to be selected for less experienced users. In this mode, the device automatically selects the welding current and wire feed speed, depending on the type of material being welded and the diameter of the electrode wire. It is possible to correct the welding voltage.

The manual mode allows the user to select the welding voltage and wire feed speed as needed.

Depending on the selected control mode and welding method, adjustment according to the table below is possible.

REGULATION OF INDUCTIVITY

Adjusting the inductance allows optimization of the arc characteristics depending on the thickness of the workpiece as well as the welding method and conditions. This function is useful when MIG / MAG welding of thin elements, preventing burn-out and during braze welding of galvanized elements.

Changing the inductance value also reduces the amount of welding spatter when welding in a CO2 shield. The higher the inductance value (+), the amount of spatter decreases, when the value is negative (-), the amount of spatter increases. The optimal setting of the inductance value depends on several factors and may differ from standard recommendations, therefore it should be chosen experimentally during welding tests.

Adjusting this parameter also allows braze welding of thin (up to 3 mm) galvanized elements made of copper alloy CuSi3 wires in a pure argon sheath or in some cases Ar / CO2 mixtures (82/18).

IGBT TECHNOLOGY

Modern technology based on bipolar transistors with an insulated gate. It combines the ease of control of field effect transistors with high breakdown voltage and switching speed of bipolar transistors. The use of IGBT technology has a significant impact on extending the reliable operation of welding equipment.

SYNERGY

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

CHANGING POLARITY

Due to the variable polarity, it is possible to weld by the FLUX method with a powder wire without shielding gas. The wire is filled with flux that produces protective gases during welding.

TIG DC LIFT

Welding with a tungsten electrode in an inert gas shield using a handle with a gas valve in the handle.

The arc is struck by rubbing just like it is when striking through the MMA method.

The application of this method enables welding of all types of steel, i.e. carbon, alloy, stainless, acid-resistant, as well as copper alloys, e.g. bronzes or brass.

The device allows you to connect a Spool Gun (SG) with a mini wire feeder and a D100 steel or colored wire spool.
