- Page 1 TIG315 AC/DC TIG WELDER OPERATION INSTRUCTIONS...
- Page 3 60% duty cycle We want you to take pride in operating our TIG315 as much pride as we have taken in making this product for you. Please read all information in this manual before operation PLEASE EXAMINE THE CARTON AND EQUIPMENT FOR DAMAGE IMMEDIATELY When this equipment is shipped, title passes to the purchaser upon receipt from the courier.
- Page 4 Welding Capability – Duty Cycle The R-Tech TIG315 is rated at 315 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 5 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 TIG315 Inverter Tig Welder requires a 415V 50/60Hz 3-Phase supply. It requires a 16A supply. It comes with a 3 metre mains cable attached.

Page 11: Controls And Settings
Controls and Settings Fig 4 1. Base current control This adjusts the main welding current and is shown in L.E.D (Fig 4.11) 2. Pulse peak current adjustment This sets pulse amperage and must be set above the base (main) current amperage. If set to zero pulse welding is disabled. - Page 12 5. AC squarewave frequency adjuster AC Squarewave frequency adjustment 20-250Hz. Traditional tig welders have a fixed frequency of 60Hz, the TIG315 advanced technology allows AC frequency adjustment from 20-250hz, as you turn up the frequency the width of arc from tungsten decreases allowing more control of weld pool and an increase travel speed The pitch noise of weld will increase when AC frequency is turned up, this is normal.
- Page 13 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. 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.
- Page 14 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. After the arc is started the output current will be at start (min) current This condition can be maintained as long as required.
