Fall time of the current ( Slope Down) - falling time of the welding current value set to zero and the current value of the crater. Range: 0 - 15s. Fall time of the current ( Slope Down) - falling time of the welding current value set to zero and the current value of the crater. Range: 0 - 15s.
Crater current ( And Stop) - current modes used in some welding when the arc is not extinguished immediately after the descent phase of the welding Crater current ( And Stop) - current modes used in some welding when the arc is not extinguished immediately after the descent phase of the welding
current. It allows you to fill the crater and the end of the weld. Range: 5 - 200A.
Ramp Time ( Up Slope) - Welding current rise time of the initial current to the set welding current. Range: 0 - 15s. Ramp Time ( Up Slope) - Welding current rise time of the initial current to the set welding current. Range: 0 - 15s.
Pulse rate ( Pulse Frequency) - the frequency with which the value of a pulse of current between the welding current and the current base. Pulse rate ( Pulse Frequency) - the frequency with which the value of a pulse of current between the welding current and the current base.
Range: 0.5 - 999Hz, we recommend setting the standard 200Hz.
Frequency AC current ( AC Frequency) - a useful feature when welding aluminum. The higher the frequency, the better weld quality and Frequency AC current ( AC Frequency) - a useful feature when welding aluminum. The higher the frequency, the better weld quality and
improved arc focus adjustment range 1 - 250Hz, we recommend setting the standard 100Hz.
Balance AC ( AC Balance) - The ratio of the duration of the positive phase to a negative power. Reducing the balance yields a greater amount of heat Balance AC ( AC Balance) - The ratio of the duration of the positive phase to a negative power. Reducing the balance yields a greater amount of heat
in the material to give a narrower and deeper weld penetration while reducing the thermal load of the tungsten electrode. Increasing the balance will
introduce less heat to the material to provide improved cleaning, wide and shallow weld penetration but heavy burden tungsten electrode. Range: 15 -
50% is recommended to set the standard of 25%.
Time powypływu gas - the time of extinction of the arc to close the gas valve in order to shield the solidifying weld pool from air and for cooling the Time powypływu gas - the time of extinction of the arc to close the gas valve in order to shield the solidifying weld pool from air and for cooling the Time powypływu gas - the time of extinction of the arc to close the gas valve in order to shield the solidifying weld pool from air and for cooling the
tungsten electrode. Too short time powypływu may result in oxidation of the weld. When welding in TIG mode, the AC (alternating current) time
should be longer. Range: 0.1 - 15s.

10. WELDING

10.1 welding with covered electrode (MMA)

10.1.1 Initiation arc

Initiation arc welding coated electrode is to touch the electrode to the workpiece, and short rubbed isolation. For initiation of the arc electrodes, wherein
the sheath when solidified, creates a non-conductive 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.

10.1.2 Keeping welding process

Welding method selection button to select the method of MMA. In this mode, you can adjust the welding current and Arc Force adjustment
function.
Welding current control is possible immediately after power-on. Turning the knob changes the welding current.
10.2. Welding gas-shielded (TIG).
10.2.1 arc initiation and conduct of TIG welding HF
Device DIGITIG 200AC / DC MULTIPRO equipped with the ionizer enabling non-contact arc ignition.
To ignite the arc mode dwutaktu must approach the electrode to the workpiece at the distance of 2 millimeters and press the button in the
handle of the burner to turn on the ionizer. Upon successful initiation of the arc
