Welding device tig ac/dc expert tig 220 ac/dc pulse lcd inverter, for aluminum; stainless for steel, 7.7kw, current max: 200a, welding method: mma / tig ac/dc

Available 2pc. EXPERT TIG 220 AC/DC is a professional inverter welding machine for TIG welding of all metals, including aluminum and stainless steel. The device enables TIG and TIG PULSE welding with alternating current (AC), direct current (DC) and MMA.

EXPERT TIG 220 AC/DC PULSE LCD is a portable power source made of IGBT technology, designed for TIG and TIG PULSE welding with alternating current (AC), direct current (DC) and direct current (DC) covered by the MMA method. electrode. Its small size and weight make the device ideal for both workshop and field work.

The device has welding modes: TIG DC, TIG DC PULSE, TIG AC, TIG AC PULSE, TIG point, MULTITAACK, TIG MIX, TIG 2-level, MMA AC, MMA DC MMA PULSE.

TIG DC and TIG DC PULS functions are used for welding stainless steel, carbon and low alloy steel, copper and titanium.

TIG AC and TIG AC PULS function: enables welding of aluminum and its alloys and brass.

TIG function of the point: allows to connect thin materials.

TIG 2-level function : "2-level" current control allows you to switch between higher and lower current levels by successively pressing the torch button.

MULTITACK function - intermittent welding, a function enabling so-called "cold welding"; welding frequency adjustment in the range of 0.5÷6.0 Hz

TIG MIX function : This is a special TIG welding method that combines direct current and alternating current, which allows full penetration and effective cleaning when welding aluminum.

By adjusting TIG PULS pulse welding parameters, we can influence the shape of the weld and the focus of the arc. Pulse welding also allows to reduce the amount of heat given to the material and is used for welding thin materials.

The arc is ignited in non-contact (HF) or touch mode (LIFT). The LIFT function is used when welding in an environment where there is a high risk that electromagnetic interference may affect the surroundings.

For both the HF contactless ignition and the LIFT touch-sensitive ignition, we can choose the TIG torch button function between 2- or 4-step operation (button lock for long welds).

The clear and easy-to-use control panel allows precise adjustment of the device, ensures stable parameters and high welding quality.

The device has 10 places for saving the user's welding programs.

The LCD display makes it easy to adjust the welding parameters:

With the MMA method, we have the option of pulse welding and adjusting its following parameters:

base current regulation
pulse frequency control
pulse width adjustment
The welder also has features that facilitate the coated electrode MMA welding process:

ARC FORCE : short-circuit current adjustment (manual) - facilitates the transfer of molten electrode drops to the welded material, preventing the arc from extinguishing when the electrode drop comes into contact with the weld half

HOT START : Hot Start Adjustment (Manual) - Facilitates electrode ignition by providing more welding current each time the arc strikes.

ANTI STICK : anti-short circuit - automatically turns off the welding voltage when the electrode sticks to the welded material, which makes it easier to tear it off and prevents the accidental formation of a welding arc

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

The fan cooling system - activated only when necessary - reduces contamination inside the device.

The quick connection of the gas to the welding torch allows the welding torch to be connected and disconnected instantly without the use of tools.

The device is equipped with overload protection, which increases its reliability.

Power parameters
Single-phase 230 V power supply. The device is equipped with a plug.
