The intensity of the arc is
proportional to the current that
flows from the tungsten. The welder
regulates the welding current to
adjust the power of the arc.
Typically thin material requires a
less powerful arc with less heat to
melt the material so less current
(amps) is required (Fig. 11), thicker
material requires a more powerful arc with more heat so more current
(amps) are necessary to melt the material (Fig. 12).
SET-UP FOR TIG WELDING
TIG welding can use DC negative or AC power.
1. Turn the power source on and select the TIG function with the TIG/MMA
selector switch (M).
1.1 Default trigger function is 2T. Switch to TIG twice in a row to
activate 4T function. The selection will display on the panel.
2. Insert the power cable plug of the TIG torch into the negative output
terminal (C) on the front of the machine and tighten it.
3. Insert the earth cable plug into the positive outlet terminal (B) on the
front of the machine and tighten it.
4. Connect the TIG torch's gas line to the gas outlet (E).
5. Connect the TIG torch's switch cable to the foot control socket (D).
6. Connect the gas line from the TIG welding machine's gas inlet (G) to the
regulator and connect the regulator to the gas cylinder.
7. Select AC or DC power with the voltage output type switch (J).
• Use DC negative power when welding steel, stainless steel, copper, etc.
• Use AC power when welding aluminum or an aluminum-based alloy.
8. Set the welding current using the amperage control dial (R). The pre-set
amperage number will appear in the digital display meter (I).
9. Set the gas pre-flow (N) and gas post-flow (Q) between 1 to 10 seconds.
10. Select the remote-control switch (K) to either the panel or to the remote
function if using a foot pedal or similar device.
11. Pulse welding options:
