5.4 Setting-up spray parameters
5.4.1 Setting-up spray voltage
• The spray voltage is adjustable at the step switch (8).
Zink = Step 1 and 2
Aluminum = Step 3, 4 and 5
• Caution!
Never switch voltage step switch while spraying.
• The spray voltage must be set high enough that a continuously
burning arc guarantees trouble-free operation.
• The stability of the available electricity network determines the uni-
formity of the arc voltage and the melting performance.
• The adhesive tensile strength of Al-coatings will be enhanced
using higher voltage (step 5).
5.4.2 Setting-up spray capacity
• The ECO ARC 600 is preset to a spray capacity of 600 A.
• The wire feed speed is regulated accordingly.
Wire feed speed <=> Spray capacity
• The maximum spaying capacity (600 A) is monitored by a pre-
adjusted current limiter relay. If this capacity is exceeded, the
system automatically shuts off. It is thereby protected from over-
load.
• In the event of overload the yellow button (3) lights. The system
can only be restarted once the fault has been acknowledged.
• The current limiting must not be changed, otherwise no protection
is guarantied.
• The air motor of the hand spray device is continuously adjustable
via the regulation screw (C) at the exhaust throttle.
So the spray capacity can be adjusted to any desired melting
capacity. The regulation screw can be adjusted by an 3 mm screw
driver.
By turning the screw clock wise (counter clock wise) the spray
capacity is increased (decreased).
• The pressure regulator for supplying the air motor is installed
inside the power supply and fixed to 5 bar. The regulator can not
be seen from the outside and must not be changed.
• The maximum capacity is only reached on work pieces with large
surface areas and for coating thicknesses in excess of 100 µm.
