CONTROL
The DELTA 160 DC 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 Anti-
freeze function.
In LIFTIG ignition the TIG arc is ignited after
making contact between the workpiece and the
tungsten electrode, after which the trigger is ac-
tivated 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 all responsibility for
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
connecting
cable and welding torch to the
machine.
