Page 46: Ac Amplitude
AC AMPLITUDE CONTROL Independent amplitude control is a very advanced feature and has many benefits, this allows the EN and EP amperage to be set independently allowing the user to direct more or less power into the workpiece and also take power / heat away from the tungsten. Increasing EN amperage while maintaining or reducing EP amperage narrows the arc allowing narrower welds and use of a smaller tungsten. - Page 47 Memory store save and load function 20 memory stores are available so you can save your preferred weld settings. To access program save menu, press the SAVE/LOAD button, the following screen will appear. Use the arrow buttons to move to required save slot. Now press and hold the SAVE button for 3 seconds, the saved program will turn YELLOW signalling the program has now been saved.

User arrow buttons to highlight setting in red, then turn control knob to adjust. AC Frequency Hz Use control knob to adjust AC Frequency, then press arrow button to move to next setting.
- Page 53 Fan control system The machine has 3 intelligent fan control modes. ON - Fan on all the time. MODE1 - Fan by thermal sensor The machine has inbuilt inverter temperature monitoring and when a certain temperature is achieved the fan will switch on to cool machine down and stop when cooling has been sufficient. This saves on power consumption and also gives a quieter working environment especially when working on thin material, so only using low amperage power.
- Page 54 Water cooler control system The machine has 3 water cooler control modes. OFF - No power to rear 240V aux power outlet. ON - Water cooler on all the time The machine will give 240V continuous output to rear power outlet MODE1 - Water cooler turned on once arc is struck The machine will start the water cooler as soon as an arc has been established, it will continue to run for 1 minute after you have finished welding..
- Page 55 Allow machine to cool down and check fan vents for obstructions E02 - Overcurrent Reset machine and if problem persists contact R-Tech support team. E05 - Shorted Trigger This will show after the torch trigger or foot pedal has been pressed and the arc has not been established after 4 seconds.
