3. Start-up
General:
Observe the notes on safety contained in these operating instructions. In addition, the
regulations on the prevention of accidents and the national regulations shall apply.
Assembling the hand-held welding and extruding machine
When dispatched, our hand-held welding and extruding machines are almost completely
assembled.
What remains to be done is to screw the enclosed handle to the machine.
For machines with external air supply the air supply hose must be connected.
Ensure sufficient supply with air which is free of oil and water (min. 300 l/min).
We recommend our air compressor, item no. DX 011.
Weld shoe
The machine is supplied with two weld shoes blank which can be machined to suit your
requirements.
Note: please observe guideline DVS 2207 part 4.
If you indicate your required form of seam and thickness of plates we will supply two weld
shoes machined ready for use.
Start-up of hand-held welding extruder
Observe the section concerning safety of these operating instructions.
Hand-held welding and extruding machines may not be used without air supply.
This would inevitably result in damages of the extruder.
Before connecting the extruder to the mains supply please check that:
-
air supply is connected correctly
-
the driving machine has not been put to permanent operation
-
now switch on air supply
-
and put plug into socket.
If you give now the power supply plug to a suitable plug socket (230V, 16A), press that
On - Off switch on the air heater on position ON.
The machine heats now up.
Make sure by each switching on of the machine, that the on-off switch of the drive
engine is switched off.
After a heating-up time of approx. 15 minutes, start the machine using the welding material
wished by you and examine the air and welding material temperature with a suitable
temperature measurement. By changing the temperature of the air heater consider the
reaction response time of the system
.
