and then set about maintenance.

The basic principles
STICK (MMA welding) - Covered electrode welding mode.
LIFT TIG (lift TIG welding) - non-consumable electrode welding mode with touch arc ignition.
HOT START - Some di ffi culties may occur when an electric arc is initiated to start the welding process. This is because both the
electrode and the welding area are cold. During start-up, for a very short period of time, the welder feeds a slightly higher current
to the electrode than was set. This allows easier arc initiation and makes the welding process more stable.
ARC FORCE (arc stabilisation) - During welding, the electrode is guided manually, which means that the distance between the end
of the electrode and the welding spot is not constant. To prevent the electrode from sticking during welding, the welder regulates
the current of the arc.
ANTI-STICK (anti-short-circuit function) - If the electrode sticks permanently during welding, the welder automatically reduces
the current to a value that allows the electrode to be detached from the weld, making it possible to continue the welding process.
VRD (Voltage Reduction Device) - This system is designed to switch o ff the power supply within a few milliseconds after welding.
It is also responsible for reducing the voltage at the covered electrode to a safe level.
DC PULSE (pulsed current) - Pulsed current welding function. The current used alternates between low and peak levels. This
makes it possible to obtain a weld with a regular shape and a fi ne-crystalline structure, eliminating weld spatter and increasing the
resistance of the joint to heat cracking.
PFC (power factor correction) - A system that improves the economy of energy consumption.
“-EH” (thermal protection) - If the thermal protection indicator marked as “-EH” fl ashes on the welder display, it is not possible
to continue welding. The indicator will automatically go o ff when the temperature drops to a level that allows further operation.
MMA welding
CAUTION! Before starting work, read the tips described in the section of the manual “Tips on how to use the MMA welding
method”.
Connect the welding cables to the correct terminals.
Connect the spring clamp to the metal part of the element to be welded. The contact area should be cleared of oil, paint or other
contaminants that may impair the fl ow of current.
Place the electrode in the torch. Regular, rutile or cellulose electrodes can be used. Place the end of the electrode without a cover
in the clamp. The electrode must be fi xed in the clamp in such a way that it is not displaced in the clamp during operation. One jaw
of the torch has notches that fi x the electrode in place.
Electrode should be selected according to the type of materials to be welded.
Ensure that the earth clamp and the electrode are isolated from each other and do not come into contact, and that the
electrode or its clamp does not come into contact with the material to be welded. Plug the power cord plug into the mains
socket. Turn the switch on the back of the unit to the “on” position (I). The welder fan will automatically switch on if the unit needs
to be cooled down. Wait approximately 3 seconds until the device is fully started. Before starting work, the operating mode and
the welding parameters must be set. The indicator light on the control panel will go on to indicate the previous welding mode and
the display (II) will show the value of the welding current in the fi eld (a) and the welding current unit (b). Brie fl y press the function
button marked with the triangle symbol pointing downwards to set the welder mode to STICK. When the light marked as STICK
goes on, this means that the welder is in MMA welding mode. Use the multifunction regulator to set the welding current appropriate
to the type and thickness of the materials to be welded in the range of 10 A - 200 A. Typical welding current values depending on
the electrode diameter are shown below.
Electrode diameter [mm]: Welding current [A]
1.6 20 – 50
2 40 – 60
2.5 60 – 80
3.2 80 – 140
4 120 – 200
To activate or deactivate the VRD function, press and hold the function button marked as MENU for approx. 3 seconds, and then
release it. If a symbol (c) on the display is on, the function is activated. Pressing the MENU button for a short time toggles the
welder parameters, and turning the multifunction knob allows the value of the selected parameter to be adjusted. Electrode type -
If a symbol (g) is shown on the display, select the electrode type in the fi eld (a) by turning the multifunction knob : E10: Cellulose
electrode E6010, E13: Rutile electrode E6013, E18: Alkaline electrode E7018. Current of the HOT START function- If a symbol (d)
