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, see chap. 7.3, p. 23.
D
Commissioning carried out, see chap. 7.4, p. 25.
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 (recommendation).
X
Calculate electrode diameter based on the max. weld current of the application.
If smaller 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 a good grinding of the electrode. Use an appropriate electrode grinding device. such as the ESG Plus tungsten
grinder (recommendation).
WARNING
Sharply ground and pointy electrodes!
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.
ATTENTION
Unintended starting of the welding procedure!
Danger of injury. Damage to materials and machine.
In the "ready to start" condition (see Fig. 14) the "Start" button could be pressed by an unauthorized
person and start the welding procedure.
X
After inserting the electrode, ensure that the "
Start
" button in the display is
not
lit red.
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 lit yellow.
The start command in test mode starts running a procedure without igniting an arc and therefore with-
out weld current; the gas valve and water 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.
