Welcome to Vector Welding my name
is Florian Wagner and in this video.
In this video please let me show you the London 2400 AC / DC TIG and MMA (Stick Type) Welder
The scope of delivery includes everything to
Vector Welding has a welder for every welding application
Here we see the London 2400
an AC/DC TIG and MMA welding machine with 200 amps
Included in the package is
A TIG welding torch type: WP17
with a 4 meter long 16 square mm cable, and a 9mm mandrel
A shielding gas quick connector and a 5 wire control cable and connector
A 3m long cable, earth clamp cable with a 16 mm square cable and a 9mm connection mandrel
An MMA electrode holder with a 3m long 16mm square cable and a 9mm connection mandrel
A flexible hose line to connect the compressed air regulator to the welder for the Plasma function
A instruction manual printed in German and English
as well as an extensive accessories package
consisting of differnet size gas nozzles sizes 4 to 7
A short and long torch end cap
A set of collets and collet holders in sizes 1.6 and 2.4 mm
To put the device into operation
first install the shielding gas hose
heat the hose end in warm water
so that the material becomes softer
this makes the hose easier to push on, then tighten the securing clamps
A quick coupler connection may be required
in order to to connect the shielding gas hose to your air compressor
this connector is no included in the scope of delivery
Connect the other end of the shielding gas hose
to the pressure reducer which is included in the scope of delivery
push the hose up on the fitting on the pressure reducer
and secure with the clamps provided
before first use it is recommended
to check the hose for leaks
check around the welding torch for leaks as well
First we will insert the control line screwed connector, pay attention
to the position of the guide nose on the
plug and tighten it hand-tight
The 9mm mandrel on the welding torch goes into the
negative power connection then the
quick coupling connector for the shielding gas line plugs in
listen for it to correctly click into place
The negative electrode goes into the positive terminal on the welder
It is important before using the welder
that you have the correct tungsten tips
for the types of materials being welded
all tungsten tip types and sizes
are NOT included in the scope of delivery
In addition, the torch angle is also
very important for your welding application
Important check that your selected tungsten
electrode slides through the collet
with no excessive play
the collets and collet holders are labeled with the
diameter of the matching tungsten
electrode, screw the collet holder into
the welding torch from below
fit the collet into the collet body
from the top of the welding torch body
the tungsten electrode should protrude
approximately 2 to 3 cm from the collet body
the electrode is fixed in postion with the burner cap
fine adjustment can be made to the "stick out" of the electrode before the cap is tightened fully
the gas cup size is selected according to the welding application
and screwed onto the torch body from below as shown
you can then fine tun the amount that
the electrode the "stick out" of the electrode from the cup
using the torch back cap
after everything has been assembled
Now let's take a look at the
setting options and parameters on the London 2400
Press the welder mode button
to switch from TIG to MMA mode and vice versa
Use the adjsutment knob to change the current setting
from 10 to 200 amps
if you are in the TIG mode
turn ON the pulse function by pressing the button in the bottom right
the maximum set current is shown on the LED display
To change more welder setting press the control knob
Press the control knob again to set pulse duration, twist the knob to adjust between 10 to 90 percent
press the control knob again t change the pulse frequency, twist the knob to adjust from 1 to 200Hz
Press the control knob to set the current reduction time, adjustable between 0.1 seconds and 10 seconds
Press the control knob to set the final current between 10 to 200 amps
Press the control knob to set the gas post flow running time from 0.1 seconds to 10 seconds
Press the control knob again to set the ac balance between 10 to 30 percent
Press the control knob again to set the ac frequency from 50 hertz to 200 Hertz
Press the control knob again to set the gas post flow time from 0.1 seconds to 5 seconds.
Press the conrol knob again to set the starting current from 10 to 200 amps
Press the control knob again to set the start current increase time from 0.1 to 10 seconds
To change to MMA (Stick Welding) mode
First connect the electrode holder into the negative current terminal on the welder
Switch the welder form TIG mode to MMA (Stick) by pressing the mode button
Adjust the control knob left or right
to set the welding current from 10 to 170 amps
Pressing the control knob will toggle through the various different MMA welder settings
The hot start strength can be set from 1 to 10
1 equals 10 amps, 5 equals 50 amps
The hot start current is always added to the welding current that has already been set
Press the control knob again to set the Hot start duration in seconds
from 1 to 10 seconds from the start of welding.
Set the duration of the hot start
in order to ignite the electrode optimally
The amps specified here are added to the welding current that was set in order to prevent the elctrode sticking
The arc force current together with the welding current can provide 170 amps maximum
Anti stick can be
adjusted from 1 to 100 amps
to prevent the electrode getting stuck to the workpiece
