CONTROL
The TIG SCOUT 160 HP machine is mainly
designed for TIG welding, and features functions
such as:
- variable slope down
- variable gas post-flow time
- option of 2-times or 4-times operation
- LIFTIG or HF-ignition can be selected
- current control from the TIG torch handle-remote
control facility
- Digital display
The machine is designed also for welding with
coated electrodes and is equipped with Antifreeze
function.
In LIFTIG ignition the TIG arc is ignited after making
contact between the workpiece and the tungsten
electrode, after which the trigger is activated and the
arc established by lifting the electrode away from the
workpiece.
In HF ignition the TIG arc is ignited without contact.
A high-frequency (HF) impulse initiates the arc when
the trigger is activated.

INITIAL OPERATION

Mains connection
The machine must be connected to a mains supply
and protection earthing. After the mains plug has
been connected to the mains supply cable (1) 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 (2) on the rear of the machine.
Dispose of the product according to local
standards and regulations.

Configuration
MIGATRONIC disclaims
damaged cables and other damages related to
welding with undersized welding torches 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.
Important!
In order to avoid damage to plugs
and cables, good electric contact is
required when connecting the work
return cable and welding torch to the
machine.
Connection of welding cables
Connect the welding cables and the return current
cable to the front of the machine.
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.
Always connect the TIG connection in the minus (-)
socket (3) and the return current cable in the plus (+)
socket (4).
The control signals from the TIG torch are trans-
formed to the machine through the circular 7-pin plug
(5). When the plug has been assembled please
secure it by turning the "circulator" clockwise.
COATED ELECTRODES: Electrodes are marked
with a polarity on the packing. Connect the electrode
holder in accordance with this marking to the plus or
minus sockets of the machine.
