Overview
Duralloy® MultiMIG 251 Inverter Double Pulse MIG 240V is a high-output multi-process machine designed for fabrication work where weld appearance, arc control and repeatability are important. Running on a 240 V 15 A supply, it combines standard MIG, pulse MIG and double-pulse MIG with MMA and lift TIG capability in a single inverter platform.
-
Suited to fabrication, aluminium work and higher-finish welding on steel and stainless
-
Works well in workshops or on sites where access to a 240 V 15 A outlet is required
-
Double pulse MIG helps manage heat input while producing a consistent, uniform bead profile
The double-pulse function allows better control on thinner materials and aluminium, helping reduce distortion while improving bead consistency and visual finish. With higher output than entry-level machines and genuine multi-process flexibility, the MultiMIG 251 is a strong fit for professional workshops and experienced operators who need controlled MIG performance from a single-phase power source.
