Tig Mode 4T; Before Calling Service - Sherman digitec DIGITIG 200AC / DC MULTIPRO User Manual

10.2.4 TIG mode 4T :

10.2.4 TIG mode 4T :
• 0 : 0 : Press and hold the handle. Starts the flow of protective gas;
• 0 ~ t1 : Time gas pre. Can be adjusted in the range of 0 ~ 1.0 sec; 0 ~ t1 : Time gas pre. Can be adjusted in the range of 0 ~ 1.0 sec; 0 ~ t1 : Time gas pre. Can be adjusted in the range of 0 ~ 1.0 sec; 0 ~ t1 : Time gas pre. Can be adjusted in the range of 0 ~ 1.0 sec; 0 ~ t1 : Time gas pre. Can be adjusted in the range of 0 ~ 1.0 sec;
• t1 : t1 : Arc ignition, is determined at start current;
• t2 : t2 : Release the handle starts to increase current set value of welding current. If you enable the pulsator, the current is modulated;
• t2 ~ t3 : Ramp Time; t2 ~ t3 : Ramp Time; t2 ~ t3 : Ramp Time; t2 ~ t3 : Ramp Time; t2 ~ t3 : Ramp Time;
• t3 ~ t4 : The welding process; t3 ~ t4 : The welding process; t3 ~ t4 : The welding process; t3 ~ t4 : The welding process; t3 ~ t4 : The welding process;
Note: If you turn on the pulsator, welding current flashes, if the pulsator is off, the welding current is constant;
• t4 : t4 : Press the handle. The welding current begins to fall to the current value of the crater. If you turn on the pulsator, falling current is
modulated;
• t4 ~ t5 : Current fall time; t4 ~ t5 : Current fall time; t4 ~ t5 : Current fall time; t4 ~ t5 : Current fall time; t4 ~ t5 : Current fall time;
• t5 ~ t6 : Current crater; t5 ~ t6 : Current crater; t5 ~ t6 : Current crater; t5 ~ t6 : Current crater; t5 ~ t6 : Current crater;
• t6 : t6 : Release the handle. Arc is extinguished, the shielding gas flows;
• t7 : t7 : The solenoid valve closes the gas flow, the completion of welding.

11. Before calling service,

In the event of malfunction of the unit, before sending welding for service, check the list of basic failures and try to remove them yourself.
Repair work may only be carried out after removing the plug from the wall socket.
Attention! The device is not sealed, and the user can remove the cover of the welding device in order to remove minor breakdowns. symptoms
The control panel is not lit, the fan
does not work, no output
The control panel lights up, the fan
does not work, no output voltage.
The control panel lights up, the fan is
working, problems with arc is started
1. Make sure the switch is in the ON position
2. Check the security on the network connection and
3. Remove the cover and check the connection of all electrical plug inside the device
1. Verify that the device has not been connected to the higher voltage. If so, connect to 230V
and turn again
2. The supply voltage is unstable and turns on the overvoltage protection. Turn off device for 2-3
minutes and then back
3. Short on and off switch may have been activated overvoltage protection. Turn off device for 2-3
minutes and then back
4. There was other damage requiring repair by an authorized service
1. Check TIG replace wear parts, if they are used
