The LOKERMANN GRAND TIG 285 DC PULSE is a three-phase inverter welding generator for TIG DC, TIG DC Pulsed and MMA welding. With HF ignition, LCD control, adjustable Hot Start and Arc Force, anti-sticking protection and 285 A at 60% duty cycle, it delivers precise and reliable welding performance for industrial fabrication and maintenance applications.

The GRAND TIG 285 DC PULSE from LOKERMANN is a three-phase inverter welding generator designed for TIG DC, TIG DC Pulsed and MMA electrode welding. Built for professional use, it delivers high-quality welds, stable HF ignition and strong duty-cycle performance for fabrication, maintenance and industrial welding applications.
Overview
The GRAND TIG 285 DC PULSE is engineered for welders who require precise TIG control, reliable electrode welding and robust industrial performance. Its large colour LCD display allows fast and intuitive machine setup, helping operators achieve high welding quality with reduced configuration time.
With excellent HF ignition, the machine is suitable for welding stainless steel, copper alloys, carbon steel and titanium. The TIG Pulse function supports high-performance welding on very thin sheets with reduced deformation, while MMA mode includes adjustable Hot Start and Arc Force for easier electrode welding. The anti-sticking function interrupts the welding current when the electrode sticks to the workpiece, improving control and protecting the welding process. The machine is equipped with temperature, voltage and current sensors and is designed to compensate for power supply voltage fluctuations, including operation when connected to a motor generator.
Recommended accessories
TIG DC and Pulse TIG performance
The machine supports TIG DC and TIG DC Pulsed welding, allowing controlled heat input and improved weld quality on thin materials. Pulse TIG is especially useful where reduced deformation and precise thermal control are required.
HF ignition
High-frequency ignition provides reliable arc starting and helps maintain clean TIG welding performance, especially in precision welding applications.
MMA welding control
In electrode welding mode, adjustable Hot Start and Arc Force help the operator achieve easier ignition, stable arc behaviour and better welding control.
Anti-sticking protection
The anti-sticking function interrupts the welding current when the electrode remains attached to the workpiece, helping protect the electrode and simplify operation.
Industrial protection and stability
Integrated temperature, voltage and current sensors help protect the machine during demanding use. The power-source design also helps compensate for voltage fluctuations, including generator-based operation.
High duty-cycle performance
With a duty cycle of 285 A at 60%, the GRAND TIG 285 DC PULSE is designed for demanding industrial use where consistent welding performance is essential.
The GRAND TIG 285 DC PULSE is suitable for:
