- Page 3 Thank you for selecting the R-Tech POWER TIG 170EXT Digital Inverter AC/DC Tig Welder. The POWER TIG 170EXT Digital has many benefits over traditional TIG welders, including 9 memory stores, advanced AC waveforms, pulse welding, slope up/down, remote foot option and an industrial 60% duty cycle.
- Page 4 Welding Capability – Duty Cycle The R-Tech POWER TIG 170EXT Digital is rated at 170 Amps at 60% duty cycle on a ten minute basis. If the duty cycle is exceeded a thermal protector will shut machine off until the machine cools.

Page 6: Electrical Installation
This machine cannot be stacked. Transport – Unloading Never underestimate the weight of equipment, never move or leave suspended in the air above people. Use recommended lifting equipment at all times. WARNING! Falling Equipment can cause injury. Never lift welder with gas bottle attached. Never lift above personnel. - Page 7 3. Direct interference radiated from feedback into power lines 4. Interference from re-radiation by un-grounded metallic objects. Keeping these contributing factors in mind, installing equipment as per following instructions should minimize problems. 1. Keep the welder input power lines as short as possible and enclose as much of them as possible in metal conduit or equivalent shielding.

Page 12: Controls And Settings
Controls and Settings Fig 4 1. Memory store function There are 9 memory store programs to enable you to select required parameters for job in hand and then store to select channel. Press memory button until required program you wish to store is showing in LED Then enter parameters as required, now press and hold save button for 3 seconds and release, the green save LED will now light for about 2 seconds and then go out. - Page 13 Adjustable from 0 - 25 seconds, this enables the backed up gas pressure to be released from torch before actual arc is started. Common settings for most application is about .3 to .5 seconds - If welding stainless steel etc sometimes a longer pre-flow is required. 4.
- Page 14 9. Pulse frequency adjustment This can be adjusted as follows: DC Mode 0.1 to 500Hz AC Advanced Squarewave 0.1 - 250Hz AC Soft Square, Triangular and Sinewave 0.1 - 10Hz Advanced AC Pulse 0.1 - 10Hz 10. AC Frequency Transformer based welders are normally fixed at 60Hz, due to the advanced inverter technology you can adjust from 20 - 250Hz.
- Page 15 HOT burst at end of weld. 14. Post Flow Gas Adjustable from 0 - 50 seconds. When you stop welding the gas will continue to flow for this set amount of time, this allows the tungsten to cool without getting contaminated and also protect the weld bead until it has cooled slightly.
- Page 16 21. Tig Pulse mode selector This machine has two pulse modes. Standard pulse works in both AC and DC modes Advanced AC pulse works only in AC mode Pulse is used to help control the amount of heat going into workpiece and commonly used on stainless steels and alloys.
- Page 17 When the trigger mode is in the 4 step position the following sequence will occur Press and hold the Tig torch switch to start sequence. The machine will open gas valve to start flow of shield gas, after preset gas pre-flow time to flow time to purge air from torch hose the welding output of machine will be turned on and the arc will be started at start (min) current This condition can be maintained as long as required.
- Page 18 by using your thumb to adjust knob on torch handle. This does take some getting used to but is handy when you are welding in a position where a foot pedal is not use-able. You can use a remote amperage torch in 2T or 4T mode, most common is 4T as you press trigger to start weld and then release you can then use thumb/finger for torch switch to adjust amperage knob, once weld has finished press the torch switch again to finish weld.
