R-Tech TIG160FPP Operation Instructions Manual page 17

Welding in TIG mode – with Pulse – No remote foot pedal
1. Connect the TIG Torch to machine, connect earth lead to machine & work piece.
2. Set to TIG mode
3. Set HF on
4. Set Pulse mode either low or high
5. Select 2-way or 4-way torch operation
6. Connect Argon gas and set flow to approx. 8 LPM
7. Set Gas post flow to minimum of 6 seconds
8. Select main welding current (Allow 30 – 35 amps per mm of workpiece)
9. Adjust Pulse amps for minimum pulse current (% of main amps)
10. Adjust Pulse freq. to desired setting (how often pulse happens)
11. Adjust Pulse time on to desired setting (how long pulse happens)
12. Press the TIG torch switch to start welding
The benefits of pulse welding are the ability to control the weld pool and amount of heat
absorbed by work resulting in a smaller heat affected zone which results in fewer deformations
and reduced chance of cracking.
