• Welding holder T-26 / 4m
• Electrode cable
• Mass cable
• User manual
• Warranty Card

TIG DC inverter welder made in IGBT technology. Designed for welding with tungsten electrodes in an inert gas shield or rutile electrodes. The welder is designed for welding using the following methods:

• MMA
• TIG DC
• TIG DC PULS

The welder has the ability to weld with a pulse and to adjust the time of the downslope and gas post-flow. The welder allows you to work with contactless (HF) arc ignition. It also has thermal protection. The device works in 2T / 4T mode and has a display showing welding parameters

It is widely used both in production and service works. The device is characterized by excellent welding properties, recommended especially for home and professional users.

The welder is equipped with a supply voltage compensation system, which enables their operation with voltage fluctuations in the supply network up to 10%.

IGBT TECHNOLOGY

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

LEVEL OF SECURITY

The IP defines the degree to which the device is resistant to solid and water contamination entering the device. IP23 means that the device is adapted to work in closed rooms and is not suitable for use in the rain.

WORK CYCLE

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

MMA

A covered electrode method consisting of a metal core covered with a sheath. The welder feeds the electrode as it fuses to the workpiece so as to keep the arc of a constant length.

HF - NON-CONTACT ARC IGNITION

The Sherman TIG 202P DC HF device is equipped with an ionizer enabling contactless arc ignition.

2T / 4T OPERATING MODE

• 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 ignition of the arc, then release the button and start welding with the released button. Pressing the button again will stop welding

INITIAL CURRENT

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.

DOWNTIME

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

RISE TIME

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

TIG PULSE

The function affects 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.

EASY TO USE, CLEAR CONTROL PANEL

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

GAS PRE-FLOW TIME

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

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.

PULSE FREQUENCY

The frequency with which the current pulse value changes between the welding current and the base current. The switch is active only during TIG welding. It is used to control the operation of the pulsator:

• Welding without a pulse
• Welding with a pulse frequency of 1.2 Hz
• Welding with a pulse with a frequency of 200 Hz

COOLING

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

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.

EASY TRANSPORT

Small dimensions and light structure make the device easy to take to any workplace. The devices are equipped with a strong handle that makes it easy to carry.
