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. Main current control
This adjusts the main welding current and is shown in L.E.D (Fig 4.9) when welding is in process.
4. Pulse frequency adjustment
This sets how often pulse will occur and is adjustable from 0.5Hz to 25Hz.
5. Gas post flow adjustment
–
Adjustable from 1
10 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.
6. MMA-TIG mode switch.
Switches between TIG (GTAW) & MMA STICK (SMAW) welding.
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
