EXPERT TIG 220 AC/DC PULSE LCD +TIG set
The EXPERT TIG 220 AC/DC is a professional inverter welder for TIG welding of all metals, including aluminum and stainless steel. The device allows TIG and TIG PULSE welding with alternating current (AC), direct current (DC), and MMA.
Technical parameters
The EXPERT TIG 220 AC/DC PULSE LCD is a portable power source, made with IGBT technology, intended for TIG and TIG PULSE welding with alternating current (AC), direct current (DC), and MMA welding with a shielded electrode in direct current (DC). Its small size and weight make the device perfect for both workshop and field work.
The device has welding modes: TIG DC, TIG DC PULSE, TIG AC, TIG AC PULSE, TIG SPOT, TIG 2-LEVEL, MMA AC, MMA DC, MMA PULSE.
The TIG DC and TIG DC PULSE functions are used for welding stainless steel, carbon and low-alloy steels, copper, and titanium.
The TIG AC and TIG AC PULSE functions allow welding of aluminum and its alloys, as well as brass.
The TIG SPOT function allows tacking of thin materials.
The TIG 2-LEVEL function: the "2-level" current regulation allows switching between higher and lower current levels by successive pressing of the button on the welding torch handle.
Thanks to the regulation of TIG PULSE welding parameters, we can influence the shape of the weld and the focus of the arc. Pulse welding also allows reducing the amount of heat delivered to the material and is used when welding thin materials.
Arc ignition occurs in a non-contact (HF) or contact (LIFT) mode. The LIFT function is used when welding in an environment with a high risk of electromagnetic interference affecting the surroundings.
Both with non-contact HF ignition and contact LIFT, we have the option to choose the function of the button on the TIG handle between working in 2-stroke or 4-stroke mode (button lock for long welds).
A clear and easy-to-use control panel allows precise device regulation, ensuring stable parameters and high welding quality.
The device has 9 user welding program memory slots.
The LCD display facilitates the adjustment of the welder's parameters:
initial shielding gas flow
initial current
current rise time
welding current
base current
current fall time
final current
final shielding gas flow
pulse width
pulse frequency
AC balance

HOT START value
ARC FORCE value
From the control panel, we can select the AC voltage waveform:
TIG AC – triangular voltage waveform
TIG AC – rectangular voltage waveform
TIG AC – sinusoidal voltage waveform
In the MMA method, we have the option of pulse welding and adjusting the following parameters:
base current adjustment
pulse frequency adjustment
pulse width adjustment
The welder also has functions that facilitate the MMA shielded electrode welding process:
ARC FORCE: short-circuit current regulation (manual) - facilitates the transfer of the molten electrode drop to the welded material, preventing arc extinction during the electrode drop's contact with the weld pool
HOT START: hot start regulation (manual) - facilitates electrode ignition by providing higher welding current at each arc ignition.
ANTI STICK: anti-short circuit - automatically turns off welding voltage if the electrode sticks to the welded material, which facilitates its detachment and prevents accidental arc formation
Physical parameters
The device has a fan cooling system that significantly increases its efficiency.
The fan cooling system - activated only when necessary - limits contamination inside the device.
Quick-connect gas connection to the welding torch allows immediate connection and disconnection of the welding torch without tools.
The device is equipped with overload protection, increasing its reliability.
Power parameters
Single-phase 230V power supply. The device is equipped with a power plug.
Equipment
The delivery includes the device with a complete set of TIG and MMA accessories: TIG 26 welding torch with remote control, 4 meters long, MMA electrode cable 3m long, ground cable 3m long.
Warranty conditions
12-month warranty for professional use. Warranty service is provided in a door-to-door system at no transport cost to the user.
