LUA 400 is a welding rectifier built on the inverter principle and designed for welding with coated electrodes, TIG welding, semi--automatic welding and arc air gouging. Advanced electronics permit rapid control, low energy consumption, excellent welding characteristics and compensation for mains voltage fluctuation.
Inverter technology contributed to the low weight and compact dimensions of then unit.

LUA 400 is the ideal choice for those who require a single power source that permits
the use of all welding methods.
The basic unit, the LUA 400 power source, can be combined with ESAB standard components to create a complete system for MIG/MAG, manual or TIG welding.

Manual welding
The high open circuit voltage and a carefully chosen ”start puff” at the beginning of welding ensure a smooth start to the welding cycle and easy striking of electrodes.
The ”anti--freeze feature” of LUA greatly reduces the risk of the electrode sticking to the work piece. If however the electrode does stick then the welding current is automatically reduced so that the electrode can be freed without damage and welding
can continue immediately. This feature facilitates the welding of root beads in particular and saves electrodes.

MIG/MAG welding
In the case of semi--automatic welding the power source must be combined with a wire feed unit, welding gun and gas bottle.
The latest electronics have been used to produce a compact, manageable and reliable semi--automatic supply with first class characteristics for MIG/MAG welding.

By using ESAB’s wide selection of semi--automatic components (wire feed units, remote controls, welding guns, counterbalance arms and cooling units) you can customise equipment to suit your welding requirements. ESAB’s special brochures describe the wide selection of semi--automatic equipment and accessories.

TIG welding
When combined with ESAB’s TIG--AID and BTD TIG gun the LUA 400 is an excellent unit for professional TIG welding.
Low current operation is essential for welding thin sheet metal. The LUA 400 satisfies this requirement, with a minimum welding current of just 15 A.
During TIG welding the ”start puff” and ”anti-- freeze” features should be switched off.
This is done by turning the rotary switch on the front panel to the ”TIG” setting.

1 Ground cabel and 1 special remote cable is included. 


P.S.
Possible to accept offers for exchange. I am interested on smaller good quality welding machine especially 1 phase (monophasic) MIG/MAG or good quality plasma cutter .
