ID 500 TW DC PULSE
Pnt Mode
It is active when TIG welding modes are selected. By pressing the trigger once, ignition starts
with the main current and the welding continues during the set time and ends automatically
at the end of this time.
• At the time the pnt mode is selected, most zones are bypassed in the TIG curve and only 3
options can be set. Final gas time, main current and spot time.
• Spot time is the welding time in the pnt mode. Allows adjustment from 0 - 20 sec.
Example :
Let the set time be 2 seconds: When you press the trigger, welding starts and continues
for two seconds and you can finish welding automatically at the end of 2 seconds without
releasing the trigger.
4- HF and VRD Mode Selection
3- Pulse Mode Selection
High frequency
• Enables welding without touching the Tungsten electrode touching the material in TIG
welding mode. By this means, the tip of the tungsten electrode will not be deformed.
• Active in TIG mode.
• If you want to switch off the HF mode on the machine and weld with the lift TIG mode,
press the HF key to switch off the active HF.
Voltage Reduction
• It ensures that the idle voltage (voltage between the output terminals) is reduced below 12V
when the machine is running and no welding is performed.
• It may be required within the framework of occupational health and safety rules.
• Applies in electrode welding modes.
• Activate or deactivate by pressing the button. The LED will light when active.
Press the button once to switch to on or off position. The LED of the corresponding function will
be active when lit.
Provides switching to the Pulse function in TIG position. Pressing the button once will switch to
active or off mode. The LED will light when active. When the pulse mode is active, the other related
functions (duty cycle, frequency amplitude, pulse frequency, etc.) become selectable.
Pulse function reduces deformation by reducing heat input to the material.
5- Welding Method Selection
You can choose between electrode types and TIG welding methods with the touch sensitive
button. The led of the relevant parameter will light up depending on which welding method is
selected.
Allows welding with cellulosic electrodes.
Allows welding with rutile and basic electrodes.
Allows DC TIG welding.
