7.3 Generator & Mobile Storage
Assembly
The System 7550 consists of a Generator assembly
(Head Assembly) and a Mobile Storage assembly
(Cart). In most cases, the two are shipped pre-
assembled. To disassemble the two, follow the
assembly steps below in reverse order. Refer to
page 2-3 of the Operator Manual.
CAUTION: The Generator (Head) assembly
is heavy and awkward. Lifting of the Head on
or off of the Cart should be done by two (2)
people to reduce the risk of injury.
Maintenance/Checkout
Section 7.0
1. Set the Head Assembly on the Cart (the argon
tanks are placed on the back of the cart).
2. Insure the Head Assembly is fully seated on
the Cart. Notice that the Head has four (4)
threaded studs that drop down into the Cart.
3. Locate the two threaded studs that are inside
the Cart, but against the back wall. Place a
wing nut on each of the two back studs, but
thread the wing nuts on the studs by only two
or three turns.
4. With one person supporting the Head, tilt the
Head Assembly towards the back of the Cart.
This allows access to the footswitch connector
and argon gas line.
CAUTION: The Head Assembly is heavy and
can topple off backwards if not supported - the
two wing nuts on the two back studs will help
with the support, but will not keep the head
from tipping the cart backwards if the head is
not properly supported.
5. Locate the wiring harness with the 15 pin
connector within the Cart. Connect the har
-
ness to the connector on the bottom of the
Head Assembly. The connector is keyed so it
can only be plugged in one way.
6. Locate the nylon argon gas tube within the
Cart. Connect the argon gas tube to the con
-
nector on the bottom of the head. The fitting
on the gas tube will “snap” into place when
inserted into the mating connector on the
bottom of the Head.
To
DISCONNECT the argon gas tube, press
the release button on the side of the fitting.
When the button is pressed, the argon gas
tube can easily be pulled out of the mating
connector. Do not pull on the gas tube as it
is easily damaged.
7. Set the Head back down onto the Cart. Add
the two remaining wing nuts to the studs
within the Cart to secure the Head to the
Cart. Insure all four (4) wing nuts are tight
-
ened.
