R-Tech TIG315, Operation Instructions Manual

12

 
Tip. If you are welding close to the tungsten limits, I.E 200amps on a 2.4mm tungsten and 
the end of tungsten is wobbling and falling off, turning down the SP% will give better 
tungsten stability 
 

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.  
 
100 - 120Hz is the ‘sweet spot’ for most AC welding. 
 

6. 

Up slope

 
Adjustment 0-10 seconds. The main welding current raises from minimum amperage to 
main current selected in time selected when weld started 
 

7. 

Pulse frequency adjustment

 
 This sets how often pulse will occur 0.5 – 25hz 
 

8. 

Pulse width

 
Pulse width adjustment – This sets length of pulse 0.1 – 0.9 seconds 
 

9. 

Down slope

 
Down-Slope adjustment 0-10 seconds. The main welding current decreases from main 
amperage to minimum amperage in time selected when weld finished 
 

10. 

Gas post flow adjustment

 
Gas post flow adjustment 1 – 25 seconds. The gas keeps flowing after weld has finished, 
this cools & stops tungsten from getting contaminated.  
Note: Gas pre-flow time is fixed at 0.5 seconds in TIG mode but no pre-flow time will occur 
if the arc is restarted during post flow time as gas is already flowing. 
 

11. 

MMA – Tig mode switch

 
MMA-TIG mode switch. Switches between TIG (GTAW) & MMA STICK (SMAW) welding 
 

12. 

AC – DC Selector switch

 
This switch selects either DC for welding steels or AC for welding alloys 
 
DO NOT SWITCH WHEN WELDING AS DAMAGE TO MACHINE CAN OCCUR. 
 

13. 

2/4 Way selector switch

 
2/4 Step trigger mode switch – tig welding can either be done in 2 or 4 step mode.
