SHERMAN-profi TIG 201P AC / DC User Manual page 7

8. protection against overheating
The power source is equipped with a thermal overload protection switch. When the temperature of the welding device is too high, the security
disconnects the welding current and the LED will overheat indicator (16). After falling temperature will automatically reset the circuit breaker.
9. WELDING coated electrodes (MMA)
9.1. Preparing for operation
Welding the wire ends to terminals (21) and (22) located on the front panel so that the electrode holder was appropriate for the electrode pole. The
return line clamp must be carefully mounted on the welded material. Plug the device into a power outlet 230V 50Hz.
9.2. Setting the welding parameters
The switch method of welding (9) to position MMA. Remote control switch (24) to the OFF position (off). Knob (3) to the desired value of the welding
current current current . . . A switch (6) to the DC position. A switch (6) to the DC position. A switch (6) to the DC position.
Switch (8) to select welding with or without pulsator pulsator. In the case of the welding of the pulsator wheel (4) to the base desired current value, the
knob (13), pulse frequency, and the knob (12) the duration of the current pulse.
9.3. initiation arc
Initiation arc welding coated electrode is to touch the electrode to the workpiece, and short rubbed isolation. For initiation of the arc electrode wherein
the sheath forms a non-conductive when solidified slag to be pre-clean the tip of the electrode by repeatedly impact against a hard surface until the
metal in contact with the work piece.
10. WELDING tungsten inert gas (TIG)
10.1. Preparing for operation
Current terminal holder should be connected to the negative pole (21), plug control handle carefully screwed to the housing (19) and the gas connection
socket connectors (18). Gas pipe reducer should be connected and attached to the gas nozzle on the rear wall of the housing. The positive pole of the
source connected to the work piece by means of a wire with a clamp. Plug the device into a power outlet 230V 50Hz.
10.2. Setting the welding parameters
The switch method of welding (9) to position TIG. Remote control switch (24) to the OFF position. and the knob (3) to the desired value of the
welding current. Switch (6) set the type of welding current.
If you intend DC welding switch should be in position DC. Switch (8) to select welding with or without pulsator pulsator. In the case of the welding of
the pulsator wheel (4) to set the desired value of the current base, the knob (13), pulse frequency, and the knob (12) the duration of the current
pulse.
Knob (5) to the desired fall time of current in the welding process.
If you intend to weld AC switch (6) to position the AC. Knob (11) to set the desired current component.
Setting parameters of gas flow:
The time rate of gas flow before the start of the welding set knob (2). The delay time of gas flow after welding set with the rotary knob (10).
