INTRODUCTION

LTN 255 are rectifiers designed using inverter technology and are intended for TIG --
welding and welding using coated electrodes.
Inverter technology contributes towards low power consumption, a low weight and
compact dimensions.
The advanced electronics with microprocessor control provides, amongst others,
quick regulation and top class welding characteristics.
LTN 255 is equipped with ARC PLUS, a new type of control that with MMA welding
provides a more intensive, more concentrated and smoother arc. It reacts quicker
after a short circuiting drop transfer, which reduces the risk of the electrode sticking.
In addition, the machine is equipped with Arc Force, which means that the power
source's dynamics can be adjusted, softer or harder depending on the type of elec-
trode and the welder's preference.
ARC PLUS -- because of the regulator's good characteristics it is only necessary to
change the Arc Force settings in exceptional circumstances.
When drop welding using stainless steel electrodes a special feature on the machine
can be activated to facilitate welding.
LTN 255 is available in two designs, one with a central connector and one with an
OKC connector for a TIG torch.
LTN 255 is supplied complete with a 5 metre mains cable, 5 metre return cable, gas
hose and hose clips. Machines with a central connector are also fitted with a safety
bar to protect the connectors from impact.
As an accessory there is a loop handle to fit on the machines which acts as a cable
reel as well protecting the control panel. There are also two carriages available for
transportation with a gas cylinder and cooling unit.
ESAB's accessories for the product can be found on page 28.
