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. -
Page 6: Electrical Installation
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 fro proper grounding methods. The high frequency generator being similar to a radio transmitter may cause interference to radio, TV and other electronic equipment. - Page 7 Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before working inside this equipment. Do not touch electrically live parts The TIG160PDC Inverter Tig Welder requires a 240V 50/60Hz 13amp fused supply. It comes with a 2 metre mains cable attached.

Controls and settings Fig 4 1. Up slope Adjustment 0-5 seconds. The main welding current raises from minimum amperage to main current selected in time selected when weld started 2. Down slope Down-Slope adjustment 0-5 seconds. The main welding current decreases from main amperage to minimum amperage in time selected when weld finished 3. - Page 12 7. Pulse On/Off switch This turns the pulse welding on and off. 8. 2/4 Way selector switch 2/4 Step trigger mode switch – tig welding can either be done in 2 or 4 step mode. When the trigger mode is in the 2 step position the following sequence will occur Press and hold the Tig torch switch to start sequence.
- Page 13 Press and hold the tig torch switch to start sequence. The machine will open gas valve to start flow of shield gas, after a 0.5 seconds pre-flow time to purge air from torch hose the welding output of machine will be turned on and the arc will be started.

• 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 •... - Page 19 • Poor weld penetration Check condition of earth lead and clamp and ensure clamp is connection via a clean area on work piece Check condition of TIG torch, try other TIG torch • Machine stuck on minimum amps when welding although higher amperage has been Make sure machine has not been set to 4-way operation as when in this mode when you press torch switch you get minimum amps and when you let go of switch machine will go to maximum amps set.
