FU01 - - FU06 Fuses fitted to the control transformer. For fuse ratings: see item 212 in the
spare parts list. Early versions of the machines have no fuses.
HL01
Lamp, 28 V, white, lights when mains power is on.
L01
Secondary inductor.
L03
Primary inductor, improves the machine's form factor, i.e. reduces the
mains load. Only included in the LTR 160.
L04, L05
Ferrite ring cores, transient voltage protection.
Replaces C10 from serial number 011- - xxx- - xxxx.
L06
Ferrite tube, transient protection for machines without shunt signal
amplifier. The shunt signal wires are twisted and wired three turns through
the tube. See
QF01
Mains power supply switch.
R01
Resistor, 3.9 kΩ 5 W.
R02
Resistor, 4.7 kΩ.
RP01
Potentiometer 500 kΩ. For gas post flow time 5 - - 20 seconds.
RP02
Potentiometer 500 kΩ. For slope down time 0.1 - - 10 seconds.
RP03
Potentiometer 10 kΩ 2 W, for setting of the welding current.
RS01
Shunt, 137 mV at 160 A respektively 200 A. The wires B1 and B2 must be
twisted in machines without shunt signal amplifier, AP10.
SA01
Switch, 2/4- -stroke changeover.
SA02
Selector switch: TIG Lift Arc / TIG HF / MMA
SA03
Switch, activation of remote control.
ST01
Thermal overload cutout, for overload protection, mounted on the main
transformer (TC02) winding. See: Thermal overload switch on page 24.
TC01
Control power transformer. Secondary output voltages of 26, 2x18, 19, 23
and 42 V.
TC02
Main transformer. For fitting instructions, see page 38.
TV01
HF coil.
V01, V02
Mains rectifier bridge, 35 A, 1200 V. V02 is only fitted in the LTR 200.
After replacing the rectifier bridges, the machine must be soft- -started: see
instructions on page 33.
