8. Operation

Caution!
Check all connections and
supply lines before switching ON.
Caution!
At the workplace, secure the
machine against rolling away.
8.1

Control unit

The operating parameters are set and
displayed at the control unit.
With the pushbutton for parameter
selection, the parameter to be displayed
or adjusted is selected.
The following parameters
selected and displayed:
− Wire feed [m/min]
− Welding current [A]
− Welding voltage [V]
− Arc length [%]
The selected parameter is indicated by
the LEDs and its value is displayed on
the 7-segment display.
Using the parameter adjustment the
desired value, except the welding volt-
age, is set.
Wire feed
Via the parameter wire feed the feed
speed of the wire feed drive is set. The
best value for welding voltage and weld-
ing current is computed by the machine,
dependent on the selected charateristics
curve.
wire feed value range:
− 1.5 ... 19 m/min.
The value range available for adjustment
is dependent on the selected electrode
wire and the operating mode.
For manual arc welding the display is
disabled.
Welding current
The best current strength is determined
by the machine. During MIG/MAG weld-
ing the welding current can not be
adjusted. The set value can be adjusted
prior to welding via the parameter adjust-
ment.
For manual arc welding it is possible to
adjust the set value of the welding cur-
rent before the welding starts and also
during the welding process (actual
value).
Welding voltage
The welding voltage is displayed only. It
can not be adjusted.
Arc length
In MIG/MAG and pulsed MIG/MAG oper-
ating mode, the value set affects welding
voltage.
The adjustment range is from 50%
through 150%. 100% is the best operat-
ing point.
Note:
When using interconnecting torch
lead extensions, the occuring voltage
drop can be compensated by the param-
eter. In this case adjust to values of
110% ... 120%.
8.2

Gas-shielded arc welding

Caution!
Check
work:
can be
− Correct electrode wire installed?
− Correct shielding gas connected?
− Welding
(liner, spiral liner, contact tip, gas
shroud, support tube)?
1. Attach earth cable at suitable loca-
tion of workpiece.
2. Open cylinder valve and set desired
gas flow rate.
Change gas shroud, if necessary.

3. Set main switch at Powerbox and
mains switch of SWK to ON.
4. Adjust the machine's default setting.
Selet charateristics curve.
5. Change parameters, if required.
The welding machine is now opera-
ble.
8.3

Manual arc welding

1. Attach earth cable at suitable loca-
tion of workpiece.
2. Set main switch of Powerbox to ON.
3. Select
KTRODE.
The welding machine is now opera-
ble.
8.4

Shutting down

1. Close gas cylinder valve.
2. Set main switch to "0 ".
3. Disconnect earth cable from the
workpiece.
4. Unplug power cable.

9. Maintenance

This welding machine contains no user-
serviceable parts.
Depending on dust accumulation, the
Powerbox and the SDV should be blown
out with condensate-free compressed
air.
Periodically check all components for
visible damage.
Contact a qualified electrician if any of
the cables are damaged.
