For TIG and Stick Welding
A total solution of precise AC/DC TIG welding machine
AC/DC London2400 is built on the base of the digital system, which offers precise, expert AC/DC TIG welding process. It?s a precise welding specialist that suits all welded materials. Modular design allows you to build the package that best suits your needs. Easy operation and full functions: From the control panel allowing fast adjustment of all necessary controls for DC, AC TIG welding with either HF or contact ignition. It?s also very convenient to store or call out the welding parameters from the memory channels by pressing the Job and Save button.
Precision Arc Performance:
DC+/DC-: Improved TIG starting. Now starts DC(-) to maintain a sharp tungsten. Lift-Arc start provides AC or DC arc starting without the use of high frequency. Adjustable AC output frequency allows the operator to focus the arc minimizing the heat affected zone. Extended AC Balance Control helps maintain a pointed tungsten to direct the arc in the weld joint. Independent amplitude/amperage control allows EP and EN amperages to be set independently to precisely control heat input to the work and electrode. Multiple Waveshapes: Standard Squarewave for fast travel speeds and excellent puddle control, Sine wave for a traditional softer sounding arc, Triangular wave to reduce the heat input into the weld at low amperage. Soft squarewave for a soft buttery arc with maximum puddle control and good wetting action, Pilot Arc for superior arc performance and easy start. HF or Non-HF Arc ignition: reliable plasma arc initiation without high frequency. Continuous Output Control: focus the arc for different material thickness. Powerful with heavy duty: 200A @50%. 10 channels memory capacity
Newly designed using the latest power electronic technology for improved reliability. CE Certified.

AC Frequency control Controls the width of the arc cone. Increasing the AC Frequency provides a more focused arc with increased directional control. Note: Decreasing the AC Frequency softens the arc and broadens the weld puddle for a wider weld bead.
AC Balance Control Controls arc cleaning action. Adjusting the% EN of the AC wave controls the width of the etching zone surrounding the weld. Note: Set the AC Balance control for adequate arc cleaning action at the sides and in front of the weld puddle. AC Balance should be fine tuned according to how heavy or thick the oxides are.
High Speed DC TIG-Pulse Controls PPS Pulses per second (Hz): DC=0.1- 5,000 PPS % ON-% Peak Time: 5-95% (Controls the amount of time during each pulse cycle at the PEAK amperage.) Background Amps: 5-99% (Sets the low-pulse amperage value as a % of the Peak Amps.)
CONVENTIONAL PULSED TIG
HIGH SPEED PULSED TIG
Typically from 1 to 10 PPS. Provides a heating and cooling effect on the weld puddle and can reduce distortion by lowering the average amperage. This heating and cooling effect also produces a distinct ripple pattern in the weld bead. The relationship between pulse frequency and travel speed determines the distance between the ripples. Slow pulsing can also be coordinated with filler metal addition and increase overall control of the weld puddle
In excess of 40 PPS, Pulsed TIG becomes more audible than visible-causing increased puddle agitation for a better as-welded microstructure. Pulsing the weld current at high speeds- between a high Peak and a low Background amperage can also constrict and focus the arc. This results in maximum arc stability, increased penetration and increased travel speeds (Common Range: 100-500 PPS). The Arc-Sharpening effects of high speed pulsing are expanded to new dimensions. The ability to pulse at 5,000 PPS further enhances arc stability and concentration potential which is extremely
Hot Start Function reliably ignites the electrode and melts perfectly to ensure the best quality even at the start of the seam. this solution makes lack of fusion and cold welds a thing of the past and significantly reduces weld reinforcement. Adjust the hot start current here and the time here.
Arcforce correction (welding characteristics)
During the welding process, arcforce prevents the electrode sticking in the weld pool with increases in current. this makes it easier to weld large-drop melting electrode types at low current strengths with a short arc in particular.

Oh no! Harry, get the glass ball!
Too bad, now we have to go back to the glass ball or read in the coffee grounds to understand our visitors ...
Why do we have to do that? Quite simply, you have forbidden us to watch Your steps on our site with Google Analytics. That sounds dramatically to You, we know. But look at it: we do not even know who YOU are, we just see that SOMEONE looks at our pages, how he/she does that, how long this SOMEONE lingers on the respective pages, etc. We do not know who You are, whether You are male or female, how old You are, how Your weight is - no idea. Nor do we pass this data on to Google, we don not have them not at all! Nevertheless, this data of SOMEONE will provide us with valuable information about our site, we want You to like everything here, that You feel good and - of course - buy our products ...
So we can see where there are problems. If many visitors leave our site during the purchase process while choosing the payment method, we know that something is wrong and can improve it. Sounds good, right? Thats good for You and good for us. So it´s a win-win situation. So let us accompany You on Your way through our store. Deal?
Thanks, Harry can pack the glass ball ...
Great, you got it! Now we can work better on our offer again!
