4. Preparing for Operation

4.1

Placing the machine

A
Caution!
Always stand the machine on
its feet only.
11
The machine draws in air at its front
12
and bottom, which is given off
13
through the ventilating slots at the
rear. Ensure an unhindered airflow.
14
The distance of the machine to walls
or other equipment must be at least
20 cm.

5. Operation

A
Caution!
Check all connections and
supply lines before turning on.

15 Note:
For manual arc welding this
machine uses the Hot-start, Arc-force
and Anti-stick functions.
Hot-start function
When contacting the weld metal with the
electrode, the set welding current is
increased for a short period to ensure
that the arc will start.
− in case of a low-voltage
condition
− in case of an over-voltage
condition
− in case of excessive an
operating temperature.
This brief increase of the welding current
is limited to the maximum electrode cur-
rent.
Arc-force function
During the welding process the machine
keeps the energy (heat) brought into the
weld metal at a constant level, even if
the distance between electrode and
weld pool varies.
Anti-stick function
If the machine detects a short-circuit in
the welding process, it will switch to min-
imum current within 0.5 sec to keep the
electrode from burning out.
5.1

Manual arc welding

1. Connect the earth cable to the –
pole.
2. Connect the welding cable to the +
pole.
A
Caution!
Note information on polarity
shown on the packaging of the elec-
trodes used; reverse polarity, if nec-
essary.
A
Caution!
For manual arc welding the
Lift-arc ignition must be disabled (not
applicable for E 140 SP/Plus). To
check, turn the rotary switch counter-
clockwise.
3. Attach earth cable at a suitable loca-
tion of the workpiece.
4. Turn master switch ON.
5. Set desired welding current.
The welding machine is now opera-
tional.
5.2

TIG welding

When using a TIG welding torch
(optional accessory), both models can
also be used for TIG welding.
1. Connect the welding current cable
of the TIG torch
(– pole).
2. Check the gas supply to the TIG
torch.
3. Attach the earth cable at a suitable
location of the workpiece (+ pole).
4. Turn master switch ON.
5. Set desired welding current.
6. Activate Lift-arc ignition.
(not applicable for E 140 SP/Plus)
To check, turn the rotary switch
clockwise.
The welding machine is now opera-
tional.
TIG welding
The arc can only be started by touching
the workpiece with the electrode (Lift-arc
ignition).
