Sherman DIGITIG PULSE AC / DC 315GD is used for manual direct and alternating current welding of structural steels with coated electrodes (MMA method) and quality steels and non-ferrous metals with a non-consumable electrode in an inert gas shield (TIG method).

In the design and construction of the device, the latest achievements in the field of PWM technology (pulse width modulation) and IGBT modules (bipolar transistors with an insulated gate) were used, thanks to which the welder is characterized by small dimensions and low weight

It is widely used both in production and service works. It is designed to work in closed and roofed rooms.

It has HF ignition, 2T / 4T function and welding current display.

The device has excellent welding properties, recommended especially for professionals.

IGBT TECHNOLOGY

The basis for the construction of the electric energy conversion system of the welding machine are electronic systems made in IGBT technology that enable operation in the frequency range above 200 kHz

2T / 4T OPERATING MODE

In the two-tact mode, pressing the switch in the handle of the handle will turn on the ionizer and ignite the arc. Welding is carried out with the switch pressed. Releasing the switch will stop welding.

In the four-cycle mode, pressing the switch in the handle of the handle will turn on the ionizer and ignition the arc, then release the switch and start welding with the released switch. Pressing the switch again will stop welding.

INITIAL CURRENT 10 - 315A

The current that appears 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 burnout. In some welding modes, the current does not increase to heat the workpiece.

HF

Tungsten electrode welding in a protective gas shield with a pilot arc (non-contact).

PULSE WIDTH 10 - 90%

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

DOWNSTREAM TIME 0 - 25s

Time for the downslope of the welding current from the set value to zero or the value of the crater current.

CURRENT RISE TIME 0 - 15s

Time in which the welding current rises from the starting current to the set welding current value.

CRATER CURRENT 10 - 315A

Current used in some welding modes when the arc is not quenched immediately after the welding current downslope. It allows you to fill the crater and the end of the weld.

BASIC CURRENT 5 - 95%

The current responsible for maintaining the welding process, the lower value of the current pulse. It facilitates the control of the amount of heat introduced into the material. Base current can only be adjusted during pulse welding.

PULSE FREQUENCY 0.5 - 200Hz

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

GAS PREFLOW TIME 0.1 - 1s

The time from pressing the button in the handle of the handle to the moment the arc is struck. Typically it should be longer than 0.5 s to deliver the shielding gas to the exit of the torch nozzle. to cover the starting point of welding and the tungsten electrode. In the case of a longer gas supply line from the cylinder, the pre-flow time should be longer.

GAS FLOW TIME 0 - 15s

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

CURRENT FREQUENCY AC 40 - 200Hz

Useful when welding aluminum. The higher the frequency, the better the quality of the weld, the better the focus of the arc

AC BALANCE 0 - 15s

The ratio of the duration of the positive phase to the negative phase. Decreasing the balance introduces more heat into the material, resulting in a narrower weld and deeper penetration, while reducing the heat load on the tungsten electrode. Increasing the balance introduces less heat into the material, resulting in better cleaning, a wide weld and shallower fusion, however, significantly stresses the tungsten electrode.

MMA

MMA welding possible

VRD FUNCTION

Module reducing the idle voltage of the device's secondary circuit. Increases safety and reduces the risk of electric shock. The function turns the welding power off and on when the resistance between the electrode tips - welded element is measured during welding.

ARC FORCE FUNCTION 0-10

It allows you to adjust the dynamics of the welding arc. Shortening the arc length is accompanied by an increase in the welding current, which stabilizes the arc. Decreasing the value results in a softer arc and a smaller fusion depth.

HOT START FUNCTION 0-10

The function is popularly known as hot start. It works when the arc is struck, causing the welding current to temporarily increase above the value set by the welder. HOT START is designed to prevent the electrode from sticking to the material and is a great help when striking the arc. In the case of welding small elements, it is recommended to disable this function, as it may cause burnout of the weld material

CLEAR DISPLAY AND EASE OF USE

The device has full regulation and control of welding parameters in real time. The adjustment is made by means of a potentiometer and buttons located on a legible and transparent so-called "soft panel".

The welder has the memory of the last settings, i.e. after turning it off and on again, the last set parameters are restored. It is also possible to save 20 sets of pulse and welding current parameter settings.

PROTECTION AGAINST OVERHEATING

The power source is equipped with a thermal automatic overload switch.

When the temperature of the welding machine is too high, the protection disconnects the welding current and the overheating diode lights up. After the temperature has dropped, the switch will reset automatically.
