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 can be

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 before starting any

work:

−Correct electrode wire installed?

−Correct shielding gas connected?

−Welding gun correctly fitted

(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 welding process ELE-

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.

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.

accessories mentioned below are rec-

ommended. These accessories have
