6. Selection for MANUAL, AUTOMATIC or HOT SPOT function
MODE
HOT SPOT
This button switches the machine from standard MIG/MAG welding mode to a specialised
process function for localised spot heating and stress relieving for metal panels.
This function is normally used in the automotive industry and light sheet fabrication. To switch
between functions, press and hold the button for 5 seconds. See further information on HOT
SPOT function later in this manual.
7. Parameter display
The large illuminated parameter display is designed to provide excellent visibility of welding
values and machine settings in a variety of welding situations. The display is protected by a
polycarbonate lens fitted into the control panel housing.
8. Overheating indicator
EN
Under normal working conditions the overheating indicator is not visible. However, should
the machine exceed its working duty cycle, welding will cease and the thermometer symbol
will illuminate indicating that the machine has overheated. The cooling fans of the machine
will continue to operate. When normal operating temperature is regained, the machine will
reset and welding can continue. The overheating indicator will no longer be visible.
9. WireLine service indicator
Under normal working conditions, the WireLine service indicator is not visible. However, if
the welding gun contact tip or liner becomes dirty and blocked or the wire feed mechanism
needs routine maintenance or the friction plates in the spool brake need adjustment or
maintenance, the Spanner service symbol will illuminate indicating that maintenance is
required. Welding is not prevented when the WireLine service symbol is active.
10. Post gas symbol
POST GAS
This symbol indicates that the post gas function is active. Kempact Regular (R) models
have fixed post gas function, but in Kempact Adaptive (A) models the post gas time can be
changed through a long press of button 13. In both models, the words POST GAS on the
display identify that the function is active.
11. Selection for materials type or display of amperes/wire feed speed (adaptive mode)
MATERIAL
A /
When operating in adaptive mode and AUTOMATIC is selected from the mode selection
button 6, a selection of filler materials types is presented through short presses of button
11. Materials selection includes FE, BRAZING, FCAW, MCAW. When selecting a suitable filler
material, POWER regulation is achieved through POWER selection knob 2. A long press (5 secs)
of button 11 also switches the display from m/min to amperes.
