Description of the London 2400 TIG Welder
The London 2400 welding machine combines high-performance AC/DC TIG welding with flexible MMA electrode welding. The high-resolution digital display, modern IGBT inverter technology, and numerous adjustment options allow for precise adaptation to different materials and welding tasks.
AC/DC TIG and MMA in a Single Welder
-
AC TIG welding: Ideal for aluminum and aluminum alloys. The adjustable AC frequency and AC balance allow for precise control of the arc, penetration, and cleaning effect.
-
DC TIG welding: Suitable for steel, stainless steel, copper, and other weldable metals.
-
MMA electrode welding: Enables robust weld joints using coated electrodes and an adjustable welding current ranging from 30 to 170 A.
High-performance welding with pulse function
-
Up to 200 A in TIG mode: Power reserves for various material thicknesses and professional applications.
-
Up to 170 A in MMA mode: Flexible use for electrode welding.
-
Pulse function: The welding current alternates in a controlled manner between the main current and the base current. This allows for precise control of heat input, penetration, and the weld pool.
-
HF ignition: Enables contactless and reliable arc ignition during TIG welding.
Precise control during aluminum welding
-
Adjustable AC frequency: Affects the focus and stability of the arc.
-
AC balance: Controls the ratio between cleaning effect and penetration when welding aluminum.
-
Pulse control: Allows for individual adjustment of pulse current, pulse width, and pulse frequency.
-
Controlled current rise and fall: Supports clean weld starts and reduces the risk of end craters.
Digital Controls and Job Memory
The high-resolution display clearly shows the selected welding parameters. Settings can be adjusted directly via the control panel to suit the specific material and welding task.
-
2-cycle and 4-cycle operation: Flexible torch control for short and longer welding jobs.
-
Job memory: Up to 9 parameter sets can be saved and quickly recalled for recurring jobs.
-
MCU Control: Fast and precise processing of the set welding parameters.
Protective functions for reliable operation
-
Hot Start: Briefly increases the welding current to facilitate electrode ignition.
-
Arc Force: Stabilizes the arc and promotes consistent material transfer.
-
Anti-Stick: Reduces the welding current if the electrode sticks to the workpiece.
-
Overheating protection: Protects the welder in case of thermal overload.
