Initial Operation - Migatronic PILOT 1800 E Manuel D'instruction

Mains connection
PILOT 1800/2400 must be connected to a mains
supply with 3 phases and protection earthing. After
the mains plug has been connected to the mains
cable (5) the machine is ready for use. Please note
that all cable connections must be made by
authorised and qualified staff. Switch on and off the
machine by means of the breaker (7) on the rear of
the machine.
Configuration
MIGATRONIC disclaims
damaged cables and other damages related to
welding with under sized welding torch and welding
cables measured by welding specifications e.g. in
relation to permissible load.
Warning
Connection to generators can damage the welding
machine.
When connected to a welding machine, generators
can produce large voltage pulses, which can
damage the welding machine. Use only frequency
and voltage stable generators of the asynchronous
type.
Defects on the welding machine arisen due to
connection of a generator are not included in the
guarantee.
Diffusion-free gas hoses
This welding machine has been mounted with a PVC
gas hose, which is sufficient for general welding
tasks. We recommend that the machine is equipped
with diffusion-free gas hoses in these special cases
where large demands have been made on gas
purity. Diffusion sealed gas hoses result in less
moisture to the protection gas. These special gas
hoses can be ordered as special equipment and
should be mounted on the supply side out to the
solenoid valve.

INITIAL OPERATION

all responsibility for
Gas connection
Connect the machine to the gas system by means of
a gas flow control. Press the gas hose mounted with
a quick connection on the gasconnection on the rear
of the machine (8).
Connection of welding cables
Connect the welding cables and the return current
cable to the front of the machine (1 and 2). Please
note that the plug must be turned 45 degrees after
insertion into the socket - otherwise the plug can be
damaged due to excessive contact resistance.
Connect always the TIG connection in the minus (-)
tap (2) and the return current cable in the plus (+) tap
(1).
The control signals from the TIG torch are trans-
formed to the machine through the circulary 7-poled
plug (4). When the plug has been assembled please
secure it by turning the "circulator" clockwise.
Connect the gas hose to the quick connection (3).
Electrodes are marked with a polarity on the packing.
Mount the electrode tongs in accordance with this
marking to the plus/minus taps of the machine (1 and
2).
Connection of external adjustment
Connect the remote control unit on the rear of the
machine on the circulary 8-poled plug (9).
Connection of a cooling module
Fastened the module under the machine with the
fitting (15). Mount the 4-poled plug (16) in the
corresponding socket in the machine (10). Mount the
flow hose on the water cooled torch in the quick
connection marked with blue (11) and the return
hose in the quick connection marked with red (12).
Control of cooling liquid and draining
The cooling liquid level can be inspected in the
inspection cover frame (13). Refillment of cooling
liquid should be carried out behind the cover (14). In
case of problems when starting up, the drain plug
(17) should be loosened.
