Brand: SHERMAN | Welding methods: TIG AC/DC, MMA | Power supply: AC 230V | Welding current: 200A | Efficiency: 25%

STANDARD EQUIPMENT

  • ShermanDIGITIG 226P AC/DC welding machine
  • Welding torch T-17/4m ERGO
  • Mass Cable
  • Instructions

DIGITIG 226P AC/DC digital welding machine is used for manual welding

  • TIG with ionization arc ignition (TIG HF) of quality steels, aluminum and other non-ferrous metals using direct and alternating current.
  • MMA (coated electrode).

The use of inverter technology has resulted in a significant reduction in the dimensions and weight of the devices, which allows their use in particularly hard-to-reach places.

The device is equipped with the option of MMA weldingwith an adjustable ARC FORCE function available. The welding machine allows full digital regulation and control of the AC current pulse and frequency parameters.

In addition, it is possible to adjust the current rise and fall as well as the gas pre-flow and post-flow. The device can be controlled remotely using a control pedal (option).

The welding machine can be used in a wide range of both production and service work.

IGBT TECHNOLOGY

The basis for the construction of the welding machine's electrical energy conversion system are electronic systems made using the IGBT technology, enabling operation in the frequency range above 200 kHz.

PROTECTION DEGREE

IP determines the extent to which the device is resistant to the penetration of solid and water contaminants. IP21S means that the device is suitable for indoor operation 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 welding machine cools down to a temperature that allows it to be turned on automatically again

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 to maintain a constant arc length.

ARC FORCE

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.

TIG AC/DC

Enables TIG welding with alternating current. This is required for welding aluminum and its alloys.

HF

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

DUTY CYCLE

The duty cycle is based on a 10-minute period. 25% duty cycle means that after 2.5 minutes of operation, a 7.5-minute break is required. A duty cycle of 100% means that the device can work continuously, without interruption.

POSTURAL CURRENT

Current responsible for maintaining the welding process, lower value of the current pulse. Makes it easier to control the amount of heat introduced into the material.

INITIAL CURRENT

Current appearing in the circuit when the button in the handle of the handle is pressed. The higher the starting current, the easier it is to strike the arc.

However, when welding thin sheets, too high an initial current value may lead to the sheet being scorched. In some welding modes, the current does not increase to heat the workpiece.

CRATER CURRENT

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

2T / 4T OPERATION MODE

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

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

CURRENT DROP TIME

Welding current decay timefrom the set value to zero or crater current value.

CURRENT RISE TIME

Welding current rise time from the initial current to the set welding current value.

TIG PULSE

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

SPOT

Spot welding – time after which welding will automatically end. Adjustment range: 0.5 – 10 s.

GAS PRE-FLOW TIME

The time from pressing the button in the handle until the arc is struck. Typically it should be longer than 0.5 s to deliver shielding gas to the burner nozzle outlet. to cover the welding start point and the tungsten electrode.

In the case of a longer tube supplying gas from the cylinder, the pre-flow time should be longer.

GAS FLOW TIME

Time from arc extinction to 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.

PULSE WIDTH

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

PULSE RATE

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

AC FREQUENCY

A function useful when welding aluminum. The higher the frequency, the better the weld quality and the better the arc focus.

AC CURRENT BALANCE

The ratio of the duration of the positive to negative phase of the current. Reducing the balance introduces more heat into the material, achieving a narrower weld and deeper penetration, while reducing the heat load on the tungsten electrode.

Increasing the balance results in the introduction of less heat into the material, achieving better cleaning, a wide weld and shallower penetration, but significantly loads the tungsten electrode.

STRONG AND SOLID CONSTRUCTION

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

COOLING

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