GRAND MIG 502 PULSE

The GRAND MIG 502 PULSE from LOKERMANN is a three-phase multi-process inverter welding power source designed for Manual MIG, Synergic MIG, Pulsed MIG, Double Pulsed MIG, Electrode and TIG DC Lift welding. Built for medium and heavy carpentry, it delivers advanced pulse control, robust welding performance and high productivity for demanding fabrication environments.

Overview

The GRAND MIG 502 PULSE is designed for professional welders who require maximum flexibility and high-quality results across multiple welding processes. Its LCD panel makes machine adjustment intuitive and helps reduce downtime during setup. The machine supports Manual MIG, Synergic MIG, Pulsed MIG, Double Pulsed MIG, Electrode and TIG DC Lift welding.

Pulsed MIG allows excellent results on aluminium alloys, stainless steels and thin sheet metal, while significantly reducing spatter. Double Pulsed MIG further reduces heat input and helps achieve a highly refined weld appearance. Synergic MIG assists the operator in finding the correct parameters with one-knob adjustment, while Arc Force and anti-sticking functions improve electrode welding control.

Technical advantages

Multi-process welding capability

The GRAND MIG 502 PULSE supports Manual MIG, Synergic MIG, Pulsed MIG, Double Pulsed MIG, Electrode and TIG DC Lift processes, making it suitable for demanding workshops that require one machine for multiple welding tasks.

Pulsed MIG performance

Pulsed MIG improves results on aluminium alloys, stainless steels and thin sheet metal while reducing spatter. This helps improve weld cleanliness and reduces post-weld finishing work.

Double Pulsed MIG control

Double Pulse further reduces heat input and supports a more refined weld appearance, making it especially useful where both mechanical quality and visual finish are important.

Synergic MIG setup

Synergic MIG helps the welder identify correct welding parameters through one-knob adjustment, reducing setup time and helping minimise parameter-related welding defects.

Electrode welding support

In electrode mode, adjustable Arc Force improves welding control, while anti-sticking interrupts welding current when the electrode sticks to the workpiece.

Heavy fabrication performance

With 500 A at 60% duty cycle and 390 A at 100% duty cycle, the GRAND MIG 502 PULSE is designed for high-output medium and heavy fabrication workloads.
