Welder Kemppi fitweld 300
Rated 300A @ 20% duty cycle, it has a 43V open circuit voltage (OCV) and can be used with mild steel solid and flux cored wires as well as stainless steel and aluminium wires from 0.8 – 1.2mm.

Features include: QuickArc™ clean arc ignition producing minimum spatter and fast arc stabilisation, the latest GT WireDrive™ to give a rapid response to welding gun trigger signals as well as for multiple arc start use, GasGuard™ automatically prevents welding when shielding gas is not present or is accidentally disconnected for the machine, and Brights™ in-built lighting, a brand new aid unique to Kemppi welding equipment, providing the welder with a cool white light to make wire spool changes and parameter adjustments easier and safer in low light working conditions.

Other features including a control panel with easy to set up voltage and wire speed arc parameters, 2T and 4T gun switch selection, strong grab handles, enclosed wire spool holder, shielding gas flow adjustment and easy polarity change, allowing either positive or negative welding, all making for faster, easier and safer welding.

MMA has long been the traditional process for tack welding in heavy industry; however it represents high labour costs due to the slow welding speeds, compared to MIG/MAG tack welding and welding speeds. The electrical energy consumed by traditional MMA machines can greatly exceed the power consumed by today’s MIG/MAG equipment; also MIG/MAG welding is cleaner and faster.

From a safety viewpoint, MMA electrodes can be a potential safety hazard as they remain potentially live when in the electrode holder, so particular care is required.
