TIG DC welder EXPERT TIG 300 DC PULSE

 

EXPERT TIG 300 DC PULSE is a professional inverter welder for TIG and TIG PULSE welding, as well as MMA welding with a coated electrode using direct current (DC). Power supply 3x400V. Welding current 10-300A.

 

Characteristics:

 

• EXPERT TIG 300 DC PULSE 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).
• 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.
• Arc ignition occurs in non-contact (HF) or contact (LIFT) mode.
• A clear and easy-to-use digital control panel allows precise adjustment, and the device ensures stable parameters and high welding quality.
• Digital parameter display
• 10 welding programs
• 2-stroke / 4-stroke

 

 

The digital display facilitates the adjustment of welder parameters:

 

• initial shielding gas flow
• current rise time
• welding current
• base current
• current fall time
• final current
• final shielding gas flow
• pulse frequency
• pulse length
• spot welding time

 

 

 

Additional device functions:

 

The welder also has functions that facilitate the welding process using the MMA method 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 - facilitates electrode ignition by providing a higher welding current at each arc strike.

 

Three-phase power supply.

 

Fan-cooled.

 

Overload protection.

 

Price of the device with a complete set of TIG and MMA accessories: TIG welding torch 4m, MMA electrode cable 3m, grounding cable 3m.
