Threading the wire and adjusting tightness
When changing the welding wire, the pressure arms need to be released. Ensure that the
groove of the feed rolls matches the diameter of ller wire used. Release the wire end
and cut o any deformed section before pulling it out from the wire feeder. Straighten
about 20 cm of the new ller wire and ensure the tip has no sharp edges. File if necessary,
as a sharp wire edge may damage the wire gun liner – particularly softer plastic liners.
Present the ller wire tip to the back of the wire feed rolls and press the wire inch button
on the wire feed front panel. Feed the wire to the gun contact tip and prepare to weld.

OPERATING MANUAL
4. USING THE WELDER
4.1 Basic controls
Main switch
When you turn the on/o switch to position 1, the main
power indicator is illuminated, and the welding system
starts a power-up sequence. The system is ready for use
when the control panel is ready. Always turn the machine
on and o with the power source mains switch. Never use
the mains plug as a switch.
Indicator lights
The indicator lights of the machine report its operational
state: When the green main power indicator is on, it indi-
cates that the machine is switched on. When the orange
warning indicator light is on, the machine is overheated.
This is due to a higher than regular working load exceed-
ing the rated duty cycle.The cooling fan continues to cool
the machine down. When the light goes o the machine
is ready to weld again.
Cooling fans
The A3 Power Source incorporates two simultaneously
operating cooling fans. The fans will start during weld-
ing as the machine reaches operational temperature, and
they will run for 1 to 10 minutes after welding, depending
on the heat eect of the completed cycle.

Control knobs 1 and 2
The left-hand control knob (1) allows the adjustment of
the speed of wire feeding. The selected speed is shown
on the display (1) on the left-hand side.
The right-hand side control knob (2) allows for control-
ling the welding voltage in MIG and 1-MIG processes, in
which case the selected voltage is shown on the right-
hand side display (2).
These control knobs are also used for specifying the oper-
ating parameters. A parameter for adjustment is selected
with the left-hand knob, while the value of the parameter
is selected with the right-hand knob.
Adjusting MIG dynamics (Arc Force)
When you press button (2), you can adjust the MIG weld-
ing dynamics of the machine by means of the knob (2).
When using the MIG or 1-MIG welding process, the weld-
ing dynamics setting aects the features of the welding
arc and the amount of welding spatter as shown below:
The value 0 is the recommended basic setting.
Use values -1...-9 if you want a softer arc and less spatter.
Use values 1...9 if you want a rougher and more stable
arc. This setting is useful when you are using 100% CO
shielding gas when welding steel.
Gas test
The gas test button (3) opens the gas valve without acti-
vating the wire feed or power source. By default, gas ows
for 20 seconds. The remaining gas ow time is shown on
the display.
The right-hand knob allows you to set the default gas
ow time, between 10 and 60 seconds, and store the new
default value in the machine’s memory. To stop the gas
test, press the ESC button (1).

13
A3 MIG Welder© Kemppi Oy 2018 1826
OPERATING MANUAL
Wire feed test
When you press the Wire inch button (4), the wire feeder
engine starts feeding. The gas valve does not open, and
the power source is not activated.
The wire feed pace is 2 m/min for the rst two seconds,
and then 10 m/min.
When the button is released, the wire feeding stops. The
machine automatically goes back to the normal state af-
ter approximately 3 seconds from release of the button or
immediately when you press the ESC button.
Retrieving weld data
The weld data function allows you to return to the weld-
ing current and voltage used during the previous session,
with the weld data feature. To use the feature, press but-
tons 3 and 4 simultaneously.
Selecting the welding process
The welding process selection button (7) allows you to se-
lect the welding process you want to use. You can select
one of the following processes:
• regular MIG welding
• 1-MIG welding
• WiseThin & WiseRoot (optional)
In regular MIG welding, the wire feed speed and weld-
ing voltage are adjusted separately. Unlike the above,
the 1-MIG, WiseThin and WiseRoot processes are synergic
welding processes where the welding voltage and other
welding parameters are interconnected so that the weld-
ing power and arc length are adjusted to attain optimal
welding values.
The WiseThin and WiseRoot processes are optional
features intended for welding automation. They must
be acquired separately by licenses and are therefore not
available in all congurations.

OPERATING MANUAL
4.3 Standard MIG features
The standard A3 MIG Welder delivery includes three MIG
features that facilitate welding and improve weld quality.
These features are creep start, hot start and crater ll.
To use a MIG feature, press the feature selector button 8.
Press the selector button repeatedly to use one or sev-
eral features. Only the features allowed for the welding
method you have chosen will be available.
Creep start (CrE)
The purpose of the creep start feature is to make con-
trolled weld start easier and smoothen the initial stage of
welding, for example when welding with high wire feed
speeds. At the beginning, the machine will use a slow
wire feed speed until the wire touches the work piece and
the current starts owing.
Creep start is available for both the regular MIG welding
and the synergic 1-MIG welding.
Hot start (Hot)
The purpose of hot start is to reduce start faults, for ex-
ample when welding aluminium or other materials with
particularly good thermal conductivity. In this scenario,
there is a xed pre-gas time at the beginning of the weld-
ing, after which the welding power briey rises above the
specied power level. The power and time parameters for
hot start can be specied in the SETUP settings.
Hot start is available for synergic 1-MIG welding.
Crater ll (CrL)
Welding Level
Crater Fill Start Level
Crater Fill Time
Crater Fill End Level
Figure 4.2 Crater ll
The purpose of crater ll is to facilitate controlled nish-
ing of welding and to reduce the welding faults caused
by the nal crater. When you press the welding gun trig-
ger completely down at the end of welding, the welding
power is reduced to a pre-set crater ll level. To end the
crater ll stage, release the gun trigger. The crater ll pa-
rameters can be specied in the SETUP settings.
Crater ll is available for synergic 1-MIG welding.

All setup parameters
The machine has several parameters, whose settings can be specied with the control
panel's SETUP function as follows:
1. Press and hold down the SETUP button (5) for at least 5 seconds.
2. Select the parameter to adjust using the left-hand side control knob. The parameter
name is shown in display left-hand display.
3. Specify the parameter value with the right-hand side control knob. The selected
value is shown in the right-hand display. The parameter’s value is immediately
stored in the memory.
4. Exit the SETUP mode by pressing and holding down the SETUP button again for at
least 5 seconds or by briey pressing the ESC button.
All welding processes have their own setup parameters. For example, adjusting the post-
current for synergic MIG welding does not aect the post-current of normal MIG weld-
ing.
The tables below show the features available in this welding machine and their possible
values.
