2T operation mode
10.1 2T operation mode (HF TIG)
1 Press and hold torch trigger to start welding
-
Open solenoid valve. Shielding gas will flow out to expel air from
torch hose (pre-gas time depends on the hose length). Then HF
ignition device works and arc starts.
- Output current continuously increases from initial current to
welding current.
2 Release torch trigger to stop welding
- Release torch trigger. Welding current will continuously decrease at
a certain rate and time until it reaches zero.
- The solenoid valve will continue to operate for a period of time
(post-gas time), allowing the shielding gas to protect the tungsten
electrode and molten pool. Then the solenoid valve closes, gas
stops and welding finishes.
10.2 4T operation mode
1 Press and hold torch trigger to start welding
-
Open solenoid valve. Shielding gas will flow out to expel air from
torch hose (pre-gas time depends on the hose length). Then HF
ignition device switches on and arc starts.
- Output current starts at initial current and time of initial current.
Output depends on the time that torch trigger is pressed and held.
2 Release torch trigger
- Output current increases from initial current to welding current. This
time is called up slope time.
- If the initial current is not required, the torch trigger does not need
to be held. Quickly press torch trigger to start arc, then quickly
release it and output current will increase to welding current.
3 Press and hold torch trigger again when the welding completes
- Welding current will continuously decrease at a certain rate until it
reaches to crater-fill current. This time is called down slope time.
-
Time of crater-fill current depends on the time that the torch trigger
is pressed and held.
4 Release torch trigger
- The output current is continuously lowered to zero and arc is
extinguished. The solenoid valve will continue to work for the
selected period of time (post-gas time), allowing the shielding
gas to protect the tungsten electrode and molten pool. Then the
solenoid valve closes, gas stops and welding completes.
