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 YOUR 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 s afe.
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 take fumes and gases away from your breathing zone
and the general area.
ARC RAYS -- Can injure eyes and burn skin.
S Protect y our 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 y our ears. Use earmuffs or other hearing protection.
S Warn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
This product is solely intended for arc welding.

3 INTRODUCTION
The Caddy Professional 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 rounded 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.

Duty cycle
The duty cycle refers to the time as a percentage of a ten--minute period that you can weld at a cer-
tain load without overloading.
Application class
The symbol indicates that the power source is designed for use in areas with increased
electrical hazard.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked IP23 is designed for indoor and outdoor use.
4.1 Equipment
Caddy Professional 250 is equipped with a remote control socket which activates
automatically when a remote control device is connected. NOTE! The contact pins L
and M must be strapped in the remote device’s connection cable for automatic
activationtofunction.Theinverterissuppliedwitha3meterlongmainscable.
Caddy Professional 250 is delivered with 5 m eter 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.

4.2 Field of application
Caddy Professional 250 supply direct current, which allows you to weld most alloyed
and non--alloyed steels, stainless steels and cast iron. With the Caddy Professional
250 you can use coated electrodes from ∅1.6 to ∅ 5 mm.
Tig--welding
TIG welding is particularly useful when high quality standards are r equired and when
welding thin sheet.
Before using the Caddy Professional 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.
5 I NSTALLATION
The installatio n must be executed b y a p rofession al.
WARNING!
This product is intended for industrial use. In a domestic environment this product may cause radio
interference. It is the user’ s responsibility to take adequate precautions.
5.1 Placing
Place the machine so that there is nothing to prevent the cooling air from passing
through it.
5.2 Connection
To get maximum performance from the Caddy Professional 250 it must be fitted with
a 16A slow fuse.
The Caddy Professional 250 have mains voltage compensation, which means that
¦10% fluctuation in the supply voltage produces only ¦0.2% variation in the
welding voltage.
Caddy Professional 250 is intended for 400V, 3 phase supplies. It can be used with
50 Hz or 60 Hz supplies.
6OPERATION
General safety regulations for the handling of the equipment can be found on
page 10. Read through before you start using the equipment!
The power switch is at the r ear of the Caddy Professional 250.
The 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 the acco mpanyin g welding cable and
return cab le, with a cross--section al area of 35 mm@. (See list of
spare parts for order number).
6.1 Overload protection
To save you worrying about overloading the Caddy Professional 250 it has a thermal
cut--out that will trip before the temperature becomes too high. You can tell when the
rectifier has been overloaded because the yellow light comes on and it will no longer
be possible to weld.
7 MAINTENANCE
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
7.1 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.
8 FAULT TRACING
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.
