CONVEX / CONVEX PULSE

PROFESSIONAL WELDING EQUIPMENT (AVAILABLE FROM JUNE 2026)

MIG-MAG INVERTER COMPACT EQUIPMENT

CONVEX and CONVEX PULSE are multiprocess compact power sources for welding in MIGMAG, MMA and TIG with “Lift” mode. Technologically ahead, robust and easy-to-use, they offer excellent quality welding in MIG/MAG and, only for CONVEX PULSE models, also in PULSED MIG and in DUAL PULSE.

CONVEX
CONVEX PULSE

Simple, powerful and compact

CONVEX and CONVEX PULSE equipment allow also less experienced operators to easily adjust all welding parameters in an intuitive way. Once the wished program is selected, the welding control automatically determines the best parameters based on the material type, wire diameter and gas.

Multi-process with great performance

These power sources represent the best choice in all industrial fields for all qualified applications requiring high precision and repeatability of the welding results especially in light  fabrication work and car body repair.

Other characteristics

  • MMA – TIG LIFT – MIG/MAG Synergic & Manual and for CONVEX PULSE: PULSED MIG and DUAL PULSE
  • Smart PROGRAM key for quickly selecting any program
  • Lodging for wire spools up to Ø 300 mm
  • Feeding mechanism with 4 rolls of large diameter for a precise and constant wire driving
  • Double groove rolls replaceable without any tool
  • “Energy saving” function to operate the power source cooling fan and torch water cooling only when necessary
