6.4 Overheating protection
The welding power source has a thermal overload trip which operates if the
temperature becomes too high, interrupting the welding current and lighting a yellow
indicating lamp on the front of the power source. The thermal overload trip resets
automatically when the temperature has fallen.
6.5 MMA welding
The CaddyArc 150 gives direct current, and you can weld most metals to alloy and
non--alloy steel, stainless steel and cast iron.The CaddyArc 150 allows you to weld
most coated electrodes from ∅1.6 to ∅3.25.
MMA welding may also be referred to as welding with coated electrodes. Striking the arc
melts the electrode, and its coating forms protective slag.
If, when striking the arc, the tip of the electrode is pressed against the metal, it immedi-
ately melts and sticks to the metal, rendering continued welding impossible.
Therefore, the arc has to be struck in the same way that you would light a match.
Quickly strike the electrode against the metal, then raise it so as
to give an appropriate arc length (approx. 2 mm). If the arc is too
long, it will crackle and spit before finally going out completely.
If you are working on a welding bench, check before attempting
to strike the arc that residual waste metal, pieces of electrode or
other objects do not insulate the part to be welded.
Once the arc has been struck, move the electrode from left to
right. The electrode must be at an angle of 60˚to the metal in
relation to the direction of welding.
When you want to weld wide beads, or when you want the weld
to be so thick that you have to weld in a number of layers, how-
ever, you have to use lateral movements.
Setting regulator -- ArcPlust
The CaddyArc 150 is supplied with ArcPlust, a new type of control that, during MMA
welding, produces a more intensive, more concentrated and calmer arc. It recovers more
quickly after a drop short--circuit, which reduces the risk of the electrode becoming stuck.

bh26d1e
Drop welding (MMA)
Drop welding can be used when welding with stainless electrodes.
This technique involves alternately striking and extinguishing the arc in order to achieve
better control of the supply of heat. The electrode needs only to be raised slightly to
extinguish the arc.
Hot Start
Hot start increases the weld current for an adjustable time at the start of welding,
thus reducing the risk of poor fusion at the beginning of the joint.
Arc Force
The arc force is important in determining how the current changes in response to a
change in the arc length. A lower value gives a calmer arc with less spatter.
Current
A higher current produces a wider weld pool, with better penetration into the
workpiece.
The current set value can be changed irrespective of which menu is displayed. This
value is displayed in the main menu only.
6.6 TIG welding
TIG welding melts the metal of the workpiece, using an arc struck from a tungsten
electrode, which does not itself melt. The weld pool and the electrode are protected
by shielding gas.
TIG welding is particularly useful when high quality standards are required and when
welding thin sheet. Caddy also has very good TIG welding characteristics.
Before using the Caddy 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 filter metal.
“Live Tig--start“
The Live Tig--start“ function strikes the arc when the electrode is brought into contact
with the workpiece and then lifted away from it.
6.7 Remote control unit
The remote control unit has to be connected to the remote control unit socket on the
power source.
If the remote control unit is not to be used, this function is removed from the panel.

7 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
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 the dust filter
SRemove the fan grille: see sketch.
SRelease the dust filter
SBlow the filter clean with compressed air (reduced pressure).
SEnsure that the filter with the finest mesh is placed towards the grille.
SReplace the fan grille with the dust filter.
8 FAULT TRACING
Try these recommended checks and inspections before sending for an authorised
service technician.
Type of fault Action
No arc. SCheck that the mains power supply switch is turned on.
SCheck that the welding current supply and return cables are
correctly connected.
SCheck that the correct current value is set.
SCheck to see whether the MCB has tripped.
The thermal overload trips ope-
rate frequently.
SCheck whether the thermal overload trips have operated
(indicated by the orange lamp on the front panel).
SCheck the main power supply fuses.
The thermal overload trip opera-
tes frequently.
SCheck to see whether the dust filter is clogged.
SMake sure that you are not exceeding the rated data for the
power source (i.e. that the unit is not being overloaded).
Poor welding performance. SCheck that the welding current supply and return cables are
correctly connected.
SCheck that the correct current value is set.
SCheck that the correct electrodes are being used.
