General Description / Initial Operation - Migatronic PILOT 200 HP Instruction Manual

GENERAL DESCRIPTION
The PILOT 200 HP is a single-phase welding ma-
chine based on inverter technology.

CONTROL
The PILOT 200 HP machine is mainly designed for
TIG welding, and features functions such as:
- Digital display
- variable slope down
- adjustable gas pre-flow and gas post-flow time
- option of 2-times or 4-times operation
- LIFTIG or HF-ignition
- Current control from:
- the control panel,
- TIG-torch
- TIG welding with pulse
- Many extra functions such as:
- start amp,
- slope up,
- pulse-frequency in special menu.
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.
Moreover, the machine is designed for welding with
coated electrodes and is equipped with Hot-start, Arc
Power and Antifreeze.

INITIAL OPERATION
Mains connection
After the mains cable has been connected, the
machine is ready for use. Please note that all cable
connections must be made by authorised and
qualified staff.
Mains voltage
230V Automatic: 35A
50/60 Hz Safety: T25A
Connection of welding cables /
Connection of TIG torch
Connect the welding cables 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 re-
sistance.
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.
Usage of the machine
When welding with PILOT 200 HP machines a
heating of various components of the machine takes
place and during breaks these components will cool
down again.
It is not possible to overload the machine in normal
use, and there is no need for cooling down periods at
current settings up to e.g. 150 A.. When the machine
is set for welding currents higher than these, there will
be a need for periods during which the machine can
cool down.
The length of these periods depends on the current
setting, and the machine should not be switched off in
the meantime. If the periods for cooling down during
use of the machine are not sufficiently long, the over-
heating protection will automatically stop the welding
process and the machine indicates overload.
The machine is ready for welding when the machine
has cooled down sufficiently. Max. load is:
100% max. load
60% max. load
30% max. load
60 % max. load means that a cooling period of 4
minutes after welding for 6 minutes is required at a
current setting of 170 Amps on a PILOT 200 HP; 10
minutes between start of each welding period must
be calculated in connection with the above table.
