SHERMAN TIG 210 ACDC PULSE WELDING MACHINE
The latest generation device, designed for professional use. It is made in IGBT technology and equipped with digital control.
The use of the inverter technology has resulted in a significant reduction in the size and weight of the devices, which allows them to be operated in places that are particularly difficult to access.
It is used for manual welding using the method
- TIG of steel and non-ferrous metals with direct and alternating current.
- MMA (covered electrode).
The welder allows full adjustment and control of all welding parameters of the arc and pulse characteristics.
During TIG welding, it is possible to adjust the upslope and downslope, gas pre-flow and post-flow, as well as pulse and AC current parameters.
It has HF ignition, 2T / 4T function and welding current display. The device has excellent welding properties and is especially recommended for professionals.
It is widely used both in production and service works. It is designed to work in closed and roofed rooms.

LEVEL OF SECURITY
The IP defines the degree to which the device is resistant to the ingress of solid and water contaminants. IP21 means that the device is adapted to work in closed rooms.
PROTECTION AGAINST OVERHEATING
The IGBT module is protected against overheating by a protective system that switches off the machine's welding circuit. After a few minutes, the welding machine cools down to a temperature that allows it to be turned on again automatically
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.
TIG AC / DC
Enables TIG welding with alternating current. It is required for welding aluminum and its alloys.
Tungsten electrode welding in a protective gas shield with a pilot arc (non-contact)
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.
THE CURRENT OF THE ATTITUDE
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.
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.
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.
2T / 4T OPERATING MODE
2T - Double-action mode - 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 - Quadruple mode - pressing the button in the handle of the handle will turn on the ionizer and arc ignition, then release the button and start welding with the released button. Pressing the button again will stop welding.
Time for the downslope of the welding current from the set value to zero or the value of the crater current.
Time in which the welding current rises from the starting current to the set welding current value.
It affects the shape of the weld and the focus of the arc. Pulse welding also allows you to reduce the amount of heat supplied to the material and is used when welding thin materials.
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.
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.
The frequency with which the current pulse value changes between the welding current and the base current.
CURRENT FREQUENCY AC
Useful when welding aluminum. The higher the frequency, the better the quality of the weld and the better the focus of the arc.
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.
STRONG AND ROBUST CONSTRUCTION
The housing of the device is made of light and durable composites, resistant to all kinds of mechanical damage.
The device has a fan cooling system, which significantly increases its efficiency
