Clarke MIG 90EN 'No-Gas' MIG Welding Machines This dual purpose machine offers the advantages of standard MIG welding but without the need for gas bottles. Although it can easily be converted to use conventional shielding gases, it is supplied with a special flux-cored wire that produces it's own gas shroud as it burns. This feature simplifys its use and makes it more suitable for outside use since there is less chance of the breeze blowing away the shrouding effect of the gas. Power settings from 24 - 90amps. Welds mild steel up to 4mm thickness. Ventilated cooling to maintain duty cycle. Uses 0.6 / 0.9mm wire up to 5Kg spools. Fully variable electronic wire speed control. Thermal overload protection with auto reset. Unit operates from 230v, 13amp domestic power supply. Everything needed for `NO GAS` welding is included - flux coated mild steel wire, professional style torch assembly, earth clamps & face shield. Easily converts to `GAS` MIG welding with optional accessories. Full instructions supplied.
