01 / Overview
MIG like you mean it.
The HELIOS SQUAD 3070 is a MIG-MAG multiprocess for workshops and professional environments that demand high performance on single-phase power: 300 amps on 220 V with a 70% duty cycle, for long, constantly demanding jobs.
Its 5" colour TFT display with HELIOS OS 1.5 provides a fast, clear interface, with synergic control that automatically sets parameters according to process, gas and wire diameter.
Developed under the THINK TANK concept, it combines structural strength with industrial functionality: MIG-MAG, FCAW, MMA and Lift TIG DC in one machine, taking 5 and 15 kg spools.
