Diodes only active during welding MMA. F pressing the control knob causes the transition between the different functions. Inflammation is a LED
indicates which function is currently regulated. Turn the knob (F) to the left or right to change the value of the function.
To enable or disable the VRD should set the value of the welding current 108A and then press the button for 3 seconds (E).
VRD backlight
To enable or disable the VRD should set the value of the welding current 108A and then press the button for 3 seconds (E).
VRD backlight
LEDs in green indicates that the VRD function is activated. Turning off the LED indicates that the option is disabled VRD.
7. PARAMETERS
7.1 MMA
After selecting the MMA it is possible to adjust the welding current, function selection and adjustment function VRD ARC FORCE and HOT START.
The welding current can be adjusted by the control knob immediately after switching on or switching the welding method. Parameters and welding
conditions can be loaded into 10 of independent memory cells (0-9) intended for the method according to item 6 MMA B and E.
VRD function
VRD function reduces the voltage in no-load. The correct voltage is restored just before arc ignition. This minimizes the risk of electric shock, but in some
cases may hinder the arc ignition. To enable or disable the VRD should set the welding current
108 A
then press the key for 3 seconds 2T / 4T (E). VRD
cases may hinder the arc ignition. To enable or disable the VRD should set the welding current
108 A
then press the key for 3 seconds 2T / 4T (E). VRD
cases may hinder the arc ignition. To enable or disable the VRD should set the welding current
108 A
then press the key for 3 seconds 2T / 4T (E). VRD
backlight LEDs in green indicates that the VRD function is disabled.
ARC FORCE
ARC FORCE allows the arc. Shortening the length of the arc is accompanied by an increase in the welding current, which results in stabilizing the arc.
Decreasing the value will give a soft arc and a smaller depth of penetration, while increasing the value results in deeper penetration and the possibility of
short-arc welding. At a set high value ARC FORCE function you can be welded while maintaining the minimum arc length and a high melting rate of the
electrode
To adjust the value of the function ARC FORCE control knob can be pressed (F) until the ignition of the respective LED. On the left is displayed on the
right of Arc and the current value of the function. Rotating the knob (F) may change the value. Range: 0 - 10
Function HOT START
HOT START function is popularly called hot start. It works when the arc is struck, causing a momentary increase in the welding current than the value
set by the welder. HOT START is designed to prevent the electrode sticking to the material and is a great help when
