6.2Overheating 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.
6.3Hidden functions
The CaddyTig 150 is supplied with ArcPlus, 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 caught.
The machine is also equipped with Arc Force, which means that the power source’s
dynamics can be adjusted, softer or harder depending on the type of electrode and
according to preference. However, the Arc Plust regulator’s good properties mean
that there is only reason to alter the Arc Force setting in exceptional cases.

7WELDING
7.1TIG welding
During TIG welding, the return cable must be connected to (+) and the T IG torch to
(--). If they are connected in reverse, the tungsten electrode will melt.
Pulsing is used for improved control of the weld pool and the solidification process. The
pulse frequency is set so slow that the weld pool has time to solidify at least partially between each pulse. In order to set pulsing, four parameters are required: pulse time,
background time, pulse current and background current.

GB
In the 2strokecontrol mode, pressing the trigger switch starts gas pre--flow (if used)
and strikes the arc (1). The current rises to the set value (as controlled by the slope
up function, if in operation). Releasing the trigger switch (2) reduces the current (or
starts slope down if in operation) and extinguishes the arc. Gas post--flow follows if it
is in operation.

Slope downGas post--
flow
In the 4strokecontrol mode, pressing the trigger switch starts gas pre--flow (if used)
(1). At the end of the gas pre--flow time, the current rises to the pilot level (a few
ampere), and the arc is struck. Releasing the trigger switch (2) increases the current
to the set value (with slope up, if in use). At the end of welding, the welder presses
the trigger switch again (3), which reduces the current to pilot level again (with slope
down, if in use). Releasing the switch again (4) extinguishes the arc and starts gas
post--flow.
7.1.3HF
The HF function strikes the arc by means of a spark from the electrode to the
workpiece as the electrode is brought closer to the workpiece.
7.1.4LiftArct
The Lift Arct function strikes the arc when the electrode is brought into contact with
the workpiece and then lifted away from it.
Striking the arc with the Lift Arc function. Step 1: the electrode is touched on to the workpiece. Step 2:
the trigger switch is pressed, and a low current starts to flow. Step 3: the welder lifts the electrode
from the workpiece: the arc strikes, and the current rises automatically to the set value.

7.1.5Current
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.
7.1.6Pulse
When activating pulse, the power source must be in the position for setting pulse
time/pause time.
1. Gas pre--flow
2. Slope up
3. Pulse current or continuous current
4. Pulse time
5. Background current
6. Background time
7. Slope down
8. Gas post--flow
7.1.7Pulse and background time
The setting range for these parameters is normally 0.01--2.5 s. However, by using micro
pulse, times down to 0.001 seconds can be set. When the micro pulse function is active,
times shorter than 0.25 seconds are displayed without a decimal point.
Micro pulse is a hidden function, to activate micro pulse, follow the description 6.3 “Hidden
function”.
Pulse time
The time the pulse current is on during a pulse period.
Background time
Time for background current which, along with the time for pulse current, gives the
pulse period.
Background current
The lower of the two current values in the event of pulsed current.

7.1.8Remote control unit
Using the remote control unit socket on the machine, the current can be controlled r emotely
for both TIG and MMA.
If pulsed current is chosen in TIG mode, it is the pulse current that is remotely controlled.
The value set from the remote control unit is shown on the display by browsing to the
position where the current would have been set without the remote control unit.
This is confirmed by the green LED lighting up.
7.1.9Gas pre--flow
This controls the time during which shielding gas flows before the arc is struck.
7.1.10Slope up
The slope up function means that, when the TIG arc strikes, the current rises slowly
to the set value. This provides ‘gentler’ heating of the electrode, and gives the welder
a chance to position the electrode properly before the full current value is reached.
7.1.11Slope down
TIG welding uses slope down, by which the current falls ’slowly’ over a controlled
time, to avoid craters and/or cracks when a weld is finished.
7.1.12Gas post--flow
This controls the time during which shielding gas flows after the arc is extinguished.

7.2MMA welding
The CaddyTig gives direct current, and you can weld most metals to alloy and non-alloy steel, stainless steel and cast iron.
The CaddyTig 150 allows you to weld most coated electrodes from ∅ 1.6 to ∅ 3.25.
The CaddyTig 200 allows you to weld most coated electrodes from ∅ 1.6 to ∅ 4.0.
If, when striking the arc, the tip of the electrode is pressed against the metal, it immediately 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 m atch.
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
cmha2p11
or other objects on the bench 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, however, you have to use lateral movements.

7.2.1Setting regulator -- ArcPlust
The CaddyTig 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.
7.2.2Arc Fo rce
The Arc Force setting alters the machine’s dynamics. A softer/harder arc can be obtained.
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.
7.2.3Drop welding
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.
7.2.4Hot 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.
