CONTROLS
Front control panel view Jasic MIG 200CS
A. Amperage digital display: Displays current when welding in either MIG and MMA mode. Please note,
in MIG mode it will show the preset wire feed speed and then welding it will display amperage.
B. Voltage digital display: Displays MIG and MMA voltage when welding. Please note that these displays
are also used to show error codes, See page 42 for further details.
C. VRD indicator: VRD is an optional facility on the MIG 200CS, please speak to your supplier for further
details.
D. 2T/4T selection switch: This option allows the user to switch between 2T (2 stroke) 4T (4 stroke/latch).
In 2T mode the weld will start and continue while the trigger is pressed. In 4T mode once the welding
arc has started can you then release the trigger and welding will continue until the trigger is activated
again.
E. Amperage and wire feed speed control: This dial has 2 functions, when in MMA mode it adjusts the
amount of welding current delivered by the power source and in MIG mode it adjusts the rate of
speed (metre per minute) at which the filler metal is fed and consumed in the weld, which in turn
adjusts the output current by varying the amount of MIG wire delivered to the welding arc. See set up
chart on page 29 for further information.
F. Voltage, arc force and downslope time control dial: Welding voltage can be adjusted in MIG mode
only and will increase or decrease the output voltage to assist in finding the optimum voltage level
required dependent on the wire feed, wire size and application being undertaken, see set up chart on
page 29.
Arc force: Functions during welding, when the machine senses a short circuit it will offer more current
to help stabilize the welding arc, this will prevent the arc from cutting out while welding as well as
preventing the electrode from sticking.
Downslope time: Used in the TIG mode and indicates the time spent on current dropping from the
preset value to 10 amps and is set according to users
’ welding requirements.
G. Welding mode selector switch: This 7 position switch allows the user to switch between MMA, TIG,
MIG and synergic MIG welding modes. See page 14 for further information.
