160 Amps Welding Capability – Duty Cycle The R-Tech TIG160PD Digital is rated at 160 Amps at 35% duty cycle on a ten-minute basis. If the duty cycle is exceeded a thermal protector will shut machine off until the machine cools.
Safety Precautions Read entire section before starting installation WARNING! Electric Shock can kill – Only qualified personnel should perform this installation. Turn off input power at the fuse box before working on this equipment. Do not touch electrically live parts. Always connect the machine to an earthed mains supply as per national recommended standards.
Electrical Installation WARNING! ELECTRIC SHOCK CAN KILL Machine grounding and High Frequency Interference Protection This welder must be grounded to earth. See national electrical codes for proper grounding methods. The high frequency generator being similar to a radio transmitter may cause interference to radio, TV and other electronic equipment.

5. The fan motor has sealed bearings which requires no maintenance Troubleshooting Service & repair should only be performed by R-Tech welding trained personnel. Unauthorised repairs performed on this welding equipment may result in danger or injury to the technician and machine operator and will invalidate your warranty.
Machine keeps overheating - Warning light is lit on machine • Check if fan is running – if not contact R-Tech for repair Check the cooling vents for obstruction, blow out machine with clean dry low pressure air supply. Check for adequate ventilation around machine Porosity in weld –...
