Page 7: 1- General Remarks
1- GENERAL REMARKS This series welding machines apply IGBT soft switch inverter technology; the power source enjoys highly stable welding voltage against the fluctuation of power grid and arc length change. The internal control system achieves precise control of welding process to ensure optimal welding results. 1-1 Power source features Highlights as follows: - Friendly operation interface, unified and separate adjustment modes, easy to master. -
Page 8: Duty Cycle
1-4 Duty cycle Duty cycle is percentage of 10 minutes that a machine can weld at rated load without overheating. If overheats, thermostat(s) will open, output stops. Wait for fifteen minutes for the machine to cool down. Reduce amperage or duty cycle before welding. -
Page 9: Warning Label
1-6 Warning label The warning label is affixed on the top of machine. Fig. 1-6-1: Warning label 2-VERSIONS BRIEFS Professional welding of special materials requires special welding parameters. Different models of the power sources are matched to different weldings. ● AMIG350/500PS Standard operation panel, easy to operate. -
Page 10: Power Source Connection
The venting duct is very important for safety protections. When choosing the machine location, make sure it is possible for the cooling air to freely enter and exit through the louvers on the front and back of machine. Any electro conductive metallic dust like drillings must not be allowed to get sucked into the machine. -
