If the coolant liquid overheats, a thermal cutoff switches the welding system off and does not allow it to be used until the coolant liquid has cooled down.
7. Coolant circulation warning
The LED is green when the coolant circulation is working normally. The LED is red when there is a problem in the coolant circulation. The LED blinks green and red in turns when the circulation of the coolant liquid has been obstructed too
long.
Caution:
If the circulation of the coolant liquid is obstructed, a thermal cutoff switches the welding system off. Check and fix the error before using the welding system again.
If the error was caused in an unsuccessful filling of the cooler, refill the cooler. In other cases, the error disappears automatically in 30 seconds.
8. Wireless pairing button
To pair the wire feeder or power source with Control Pad, press the button. If the power source is connected to wire feeder(s), the wire feeder(s) pairs with Control Pad. If the power source is not connected to a wire feeder, the power source pairs with Control Pad.

2.3.3 Wire Feeder installation
This chapter describes the wire feeder installation.
For wire feeder cable connections, see Installing interconnection cable. For information on operating the wire feeder, see Wire feeder control panel on page 96.
Caution:
Welding quality and efficiency are greatly dependent on the consumable parts used on the wire line. These include the wire guide tubes, feed rolls, wire liners, gas nozzles and contact tips. Always ensure that you are using the correct consumable parts suitable for the filler wire size and material.
For more information, visit Kemppi consumable kit selection site at kitselect.kemppi.com.
2.3.3.1 Installing wire feeder
The installation of the Wire Feeder Rotating Plate and Double Wire Feeder Rotating Plate is identical, as is installing one or two wire feeders.
Install the wire feeder on the power source with a Wire Feeder Rotating Plate. To install two wire feeders, use a Double Wire Feeder Rotating Plate.
Note: To set up the system for double wire feeder configuration, you need certain assembly parts. For more information, see Double wire feeder assembly parts.

spool. Tighten if necessary.
Note:
The spool brake is equipped with an optional wire tensioning feature, which keeps the wire feed steady in short repeated welds and with heavy wire spools. To enable wire tensioning, attach the spool brake hub to the wire spool so that the tightening knob is on the right, seen from the front.
Lower the wire spool to its socket.
9.
Note:
Ensure that the wire spool is facing the right direction, the filler wire running from the top of the spool to the feed rolls.
Lift the pressure handle off of the feed rolls.
10.
Install the filler wire:
OPERATING MANUAL | EN 45

KEMPPI | 2018-09-28
X8 MIG WELDER 2.3 Installation
Release the pressure arms to move the feed rolls apart. This opens a gap between the feed rolls.
11.
Release the filler wire end from the spool and cut off any deformed section so that the end is straight.
12.
Note:
Ensure that the filler wire does not spill from the spool when it is released.
File the tip of the filler wire smooth.
13.
Caution:
Sharp edges on the filler wire tip may damage the wire liner.
Guide the filler wire through the inlet tube (A) and middle wire guide tube (B) to the outlet, which feeds
14.
the filler wire to the welding gun. Push the filler wire by hand inside the gun so that the wire reaches the wire liner (about 20 cm).
Close the pressure arms so that the filler wire is locked between the feed rolls. Ensure that the filler wire
15.
sits in the feed roll grooves.
Lower the pressure handle on the feed rolls.
16.
Adjust the pressure of the feed rolls with the pressure adjustment wheels. The pressure is the same for
17.
both feed roll pairs. The graduated scales on the pressure handle indicate the pressure applied to the feed rolls. Adjust the
pressure of the feed rolls according to the table below.

2.4 Operation
Follow these operating instructions carefully to have full advantage of your X8 MIG Welder and to minimize the risk of malfunctions.
2.4.1 X8 MIG Welder control devices
Welding with X8 MIG Welder can be controlled through three different control panels, which offer slightly different features for adjusting the welding parameters.
The actual features vary according to the functions and usability of the control panel.
2.4.1.1 Control Pad
Control Pad is a window to X8 MIG Welder: Control Pad shows you all the settings and licenses installed in the welding system.
You can adjust the welding parameters and their values remotely with the one-knob navigation, and connect Control Pad to any X8 MIG Welder nearby.
Navigation
Above the display, Control Pad has three view buttons. Press these buttons to change the view on Control Pad's display. Press the Menu button twice to open the View menu.
Use the knobs under the display to move in the display and to adjust the values. When there is a green light in the center of the knob, the knob also functions as a push button.

System settings
The options under System settings are:
1. Water cooling
Set water cooling ON, OFF or on AUTO. In ON mode, the water cooling is continuous. In OFF mode, the water cooling is fully stopped. In AUTO
mode, the water cooling is on when needed.
2. Sub feeder selection
Select the sub feeder you are using and its length, or the motorized gun.
3. WF Motor warning level
Select a limit for the welding current. The system warns you, if the value exceeds the limit.
4. Voltage display mode

5. Safe wire inch
Set the Safe wire inch ON or OFF. If the Safe wire inch is ON, the wire feeder feeds maximum 5 cm of the wire, if the arc does not ignite until then. If the Safe wire inch is OFF, the wire feeder feeds maximum 5 m of the wire. This is to prevent the wire from hitting the welder.
6. Voltage reduction device (VRD)
Switch VRD ON or OFF if you are using MMA or gouging process. VRD reduces the maximum unloaded open circuit voltage across the output terminals of the welding machine to a safe voltage.
