TIG DC welder EXPERT TIG 200 DC PULSE

 

EXPERT TIG 200 DC PULSE

 

It is a professional inverter welder for welding using the TIG and TIG PULSE methods, as well as the MMA method with a coated electrode using direct current (DC). Power supply 230V. Welding current 5-200A.

 

CHARACTERISTICS:

 

Technical parameters:

 

• EXPERT TIG 200 DC PULSE is a portable power source, made with IGBT technology, designed for welding using the TIG and TIG PULSE methods, as well as MMA welding with a coated electrode using direct current (DC). Its small size and weight make the device perfect for both workshop and field work.
• The device has three welding modes: TIG DC, TIG DC PULSE, MMA.
• The TIG DC and TIG DC PULSE functions are used for welding stainless steel, carbon and low-alloy steels, copper, and titanium. Welding is performed in an inert gas shield.
• Thanks to the adjustment of TIG DC PULSE pulsed welding parameters, we can influence the shape of the weld and the focus of the arc. Pulsed welding also allows for a reduction in the amount of heat delivered to the material and is used when welding thin materials.
• Arc ignition occurs in either non-contact (HF) or contact (LIFT) mode. The LIFT function is used when welding in environments with a high risk of electromagnetic interference affecting the surroundings.
• Both in non-contact HF ignition and contact LIFT ignition, we have the option to choose the function of the button on the TIG torch between 2-stroke or 4-stroke mode (button lock for long welds).
• A clear and easy-to-use digital control panel allows for precise device adjustment, ensuring stable parameters and high welding quality.

 

The digital display facilitates the adjustment of welder parameters:

 

• initial shielding gas flow
• initial current
• current rise time
• welding current
• base current
• current fall time
• final current
• final shielding gas flow
• pulse length
• pulse frequency
• intermittent welding length
• HOT START adjustment
• ARC FORCE adjustment

 

The welder also has functions that facilitate the MMA welding process with a coated electrode:

 

• ARC FORCE: short-circuit current adjustment - facilitates the transfer of the molten electrode drop to the welded material, preventing the arc from extinguishing when the electrode drop contacts the weld pool
• HOT START: hot start adjustment - facilitates electrode ignition by providing a higher welding current at each arc ignition.
• ANTI STICK: anti-short-circuit - automatically turns off the welding voltage if the electrode sticks to the welded material, making it easier to detach and preventing accidental arc formation
• VRD (Voltage Reduction Device) function - reduces the no-load resting voltage on the electrode to a safe level. Ensures anti-shock safety when working in humid environments.

 

Physical parameters:

 

• The device has a fan cooling system, which significantly increases its efficiency.
• The quick-connect gas connection to the welding torch allows for immediate connection and disconnection of the welding torch without the use of tools.
• The device is equipped with overload protection, which increases its reliability.

 

Power supply 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 metres long, MMA electrode cable 3m long, and ground cable 3m long.

 

Warranty conditions:

12-month warranty for professional use. Warranty service is provided in a door-to-door system with no transport costs for the user.
