2SAFETY
WARNING
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU-
TIONS WHEN WELDING. ASK FOR Y OUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ HAZARD DATA.
ELECTRIC SHOCK -- Can kill
S Install and earth the welding unit in accordance with applicable standards.
S Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
S Insulate yourself from earth and the workpiece.
S Ensure your working stance is safe.
FUMES AND GASES -- Can be dangerous to health
S Keep your head out of the fumes.
S Use ventilation, extraction at the arc, or both, to keep fumes and gases from your breathing zone and
the general area.
ARC RAYS -- Can injure eyes and burn skin.
S Protect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
S Protect bystanders with suitable screens or curtains.
FIRE HAZARD
S Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE -- Excessive noise can damage hearing
S Protect your ears. Use ear defenders or other hearing protection.
S Warn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!

3 INTRODUCTION
Note!
This product is solely intended for arc welding.
The LHN 250 are one transistor controlled welding power source designed for
welding with coated electrodes and for TIG welding (touch start).
The advanced electronics provide r apid control response, low power demand and
excellent welding characteristics. Inverter technology contributes to low weight and
compact dimensions of the units.
The r ounded slimline shape of the unit makes it comfortable to carry. The strap can
be folded to serve as a carrying handle, or fully extended to serve as a shoulder
strap.

*When welding below 100 A a 10 A slow fuse is adequate..
**Power cable ratings complies with Swedish regulations..
Duty cycle
The duty cycle refers to the tim e in per cent of a ten--m inute period that you can weld
at a certain load without overloading the welding power source.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against
penetration by solid objects or water. Equipment marked IP 23 is designed for indoor
and outdoor use.
Application class
The symbol indicates that the power source is designed for use in areas where
there is an increased electrical hazard.

3.2 Equipment
LHN 250 is equipped with a remote control socket which activates automatically
when a remote control device is connected. NOTE! T he contact pins L and M must
be strapped in the remote device’s connection cable for automatic activation to
function.Theinverterissuppliedwitha3meterlongmainscable.
LHN 250 is delivered with 5 meter long welding and return cables. These are
attached to cable connectors allowing quick change of polarity.
The manufacturer’s serial number is stamped on the rating plate.
3.3 Field of application
LHN 250 supply direct current, which allows you to weld most alloyed and
non--alloyed steels, stainless steels and cast iron.
With the LHN 250 you can use coated electrodes from 1.6 to 5 mm.
Tig--welding
TIG welding is particularly useful when high quality standards are required and when
welding thin sheet.
Before using the LHN 250 for TIG welding it must be equipped with a TIG torch and
gas valve, a cylinder of argon, an argon regulator, tungsten electrodes and, if
necessary, suitable filler metal.
The best method to use is the touch start, where you gently stroke the tungsten
electrode against the workpiece to establish the arc.
4 INSTALLATION
WARNING
This product is intended for repair and maintenance welding
In domestic or office environment this product may cause radio interference.
It is the responsibility of the user to take adequate pr e cautions.
4.1 Placing
Place the machine so that there is nothing to prevent the cooling air from passing
through it.
4.2 Connection
To get maximum performance from the LHN 250 it must be fitted with a 16A slow
fuse.
The LHN 250 have m ains voltage compensation, which means that ¦10%
fluctuation in the supply voltage produces only ¦0.2% variation in the welding
voltage.
LHN 250 is intended for 400V, 3 phase supplies. It can be used with 50 Hz o r
60 Hz supplies.

5OPERATION
5.1 Start--up
The power switch is at the rear of the L HN 250. T h e white lamp on the fr ont will glow
when the power is on.
1. Yellow lamp
2. Welding current control 4--250 A
3. White lamp
4. Remote control socket
The current is adjusted using the knob on the front.
Important!
Only use th e accompanying welding cable and return cable, with a
cross--sectional area of 35 mm@.
(See list of spare parts for order number).
5.2 Overload protection
To save you worrying about overloading the LHN 250 it has a thermal cut--out that
will trip befo re t he temperature becomes too high. You can tell when the rectifier has
been over loaded because the yellow light comes on and it will no longer be possible
to weld.
6 MAINTENANCE
6.1 Cleaning
Normally it is sufficient to blow the welding power source clean regularly using dry
compressed air (reduced pressure), and to clean the filter in the front regularly.
In dusty and dirty environment the welding power source should be cleaned at
shorter intervals.

7 FAULT TRACING
7.1 Possible faults and measures to take
Type of fault Measure
No arc is generated by the welding power
source.
S Make sure the mains switch is on.
S Check that the welding and return cables
are properly connected.
S Make sure the welding current set is correct.
The welding current is interrupted in the course
of welding.
S Check if the thermal cut--out has tripped (the
orange indicating lamp on the front panel is
on).
S Check the mains fuse.
The thermal cut--out trips frequently. S Check that the filter is not packed with dust.
S Check that the ratings of the welding power
source have not been exceeded (overload
of the power source).
Poor welding result. S Check that the welding and return cables
are properly connected.
S Make sure the welding current set is correct.
S Check that there is nothing wrong with the
electrodes.
