Since it requires no gas cylinder, the flux-cored wire encloses the shielding gas within the wire itself: this also makes it suitable for outdoor work and windy conditions, where a wire welder with external gas would lose effectiveness as the shielding flow gets blown away. The synergic wire feed automatically adjusts speed to the set current, simplifying use even for less experienced welders; manual control remains available for those who prefer direct adjustment.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Güde range\u003c\/h3\u003e\n\u003cp\u003eWithin the Güde inverter welder range, the SG 121 A-SYN is a model dedicated exclusively to flux-cored wire, with synergic feed and current up to 120 A. Flux-cored wire is also available on the GIS 200, a multi-process model covering MIG\/MAG, MMA, flux-cored wire and optional TIG up to 200 A: anyone who only needs flux-cored wire, without the other processes, will find the SG 121 A-SYN more compact, easier to handle thanks to automatic synergic control, and specifically designed for gasless use on site or outdoors.\u003c\/p\u003e\n\u003ch3\u003eKrollit logistics and support\u003c\/h3\u003e\n\u003cp\u003eShipping in 3-5 working days from Krollit's warehouse in Monteforte Irpino (AV), Italy.
