Testing the procedure

8.2.1

Preparing weld head

These operating instructions can only provide basic information on the most commonly used weld heads (due to the
variety of tools which can be connected).
In the following, the important actions for so-called "open" weld tongs and cassette heads are listed.
X Refer to detailed information on preparing the operating instructions of the weld head.
D Gas bottle and weld head connected, siehe Kap. 7.4, Seite 99.
D Commissioning carried out, siehe Kap. 7.5, Seite 100.
D Machine switched on.
8.2.2

Preparing electrode

For almost all Orbitalum weld heads, electrodes with a diameter of 1.6 mm (0.063") and 2.4 mm (0.094") can be used.
X For "Micro head" type OW 12: Use only electrodes with a 1.0 mm (0.039") diameter.
X Up to a current of approx. 100 amperes (high-pulse): Use electrodes with a 1.6 mm (0.063") diameter (recommen-
dation).
X Calculate the electrode diameter based on the max. weld current of the application.
If lower currents are used, the use of 2.4 mm (0.094") electrodes can lead to a worsening of the
ignition characteristics and "wandering" of the arc at the electrode.
X Ensure good grinding of the electrode. Use an appropriate electrode grinding device. such as the ESG Plus tungsten
grinder (recommendation).
Sharply ground and pointy electrodes!
WARNING!
Danger of injury.
X Store ground electrodes so that there is no danger of injury.
8.2.3

Turning weld head

You can turn the weld heads with a motor for insertion of the electrode.
Clamping of fingers possible during manual moving.
CAUTION!
X During clamping in move the rotor electrically in the opposite direction.
Unintended starting of the welding procedure!
CAUTION!
Danger of injury. Damage to materials and machine.
In the "ready to start" condition (see Abb. 6) the "Start" button could be pressed by an unauthor-
ized person and start the welding procedure.
X Switch off the welding power supply for electrode replacement.
X After inserting the electrode ensure that the "Start" button in the display does not have a red
background.
X Only use the function for motor movement from the "red" start area if the weld head is being
moved immediately before starting the process, e.g. to change the starting position.
"Test mode" is indicated by the "Start" button having a yellow background.
The start command in test mode starts running a procedure without igniting an arc and therefore with-
out weld current; the gas valve and coolant pump are switched off. You can use this "dry run" to check
the change in level at the intended points on the pipe and the run of the motor.
