ESAB has published a guide for their portfolio of compact MIG/MAG welding machines, including the Aristo, Caddy and Origo ranges. The literature is illustrated, showing models currently available and their suitability for use on mild steel, stainless steel and aluminum. It also discusses functions including polarity change, the Qset facility for automatic setting of the weld parameters, and spot weld timers. Readers can also see what main voltages are necessary and what the maximum current output is for each model.
