Our aim is to advance welding to the highest possible level. With 55 years of experience, we are once again setting the standard for the future of welding. We are doing this with the development of the HighPulse Touch series.
But what makes the new HighPulse Touch welding machine unique?

HighPULSE touch – Merkle's most sophisticated welding technology! The HighPULSE touch family combines high-speed welding with the particularly advantageous TEDAC system : in both the portable 280/350 K models and the 400 KW/DW and 450 KW/DW models designed for industrial use.
One of the best examples of Merkle's versatility in product development is the TEDAC® system, which provides continuous power control and feedback at the torch. It simplifies and speeds up welding in difficult-to-reach places.
The undisputed advantages of the HighPULSE touch series are its ease of use, extensive choice of programmes and power control directly from the torch.
Merkle HighPULSE touch. A revolution in pulsed arc welding!

The portable HighPULSE touch 280/350 K (available with an optional water cooler and trolley).

The compact, easily manoeuvrable HighPULSE touch 400/450 KW with integrated water cooling system.

HighPULSE touch 400/450 DW with separate wire feeder for larger workpieces.

This makes welding particularly efficient and economical. As standard, the complete HighPULSE touch software package includes Merkle processes such as DeepARC, ColdMIG and HighUP.
Programmes for low-alloy steels, stainless steels and aluminium alloys, for example, are included as standard at no extra cost.

DeepARC. Faster welding with deeper penetration and less spatter.

ColdMIG ! Perfect for thin sheet metal and applications requiring substantial gap bridging.

HighUP! Vertical welding made easy!


All the welding machine's controls are directly accessible from the front of the machine. Arc length and power can also be adjusted from the separate wire feeder.

The complete control panel can be integrated into the separate wire feeder. This makes operation easier and provides greater flexibility, even in hard-to-reach places.

Power can be adjusted continuously from the TEDAC® torch.

Various parameters can be adjusted easily and continuously. The desired value can be set by dragging to the appropriate position with a finger. Alternatively, parameters can still be adjusted using the rotary push-button, by turning it and then pressing it.

Numerous other parameters can be set to the desired value from the "Settings" menu.

Inductance, pulse shape, wire burnback, gas pre-flow and post-flow, starting and end current, and downslope time can all be set to the desired values.

Increased performance, unique intuitive operation and excellent value for money make HighPulse TOUCH welding machines an economical choice.

A lockable control panel cover is available as an option.

Prepared for MMA welding with electrodes up to 6 mm. Hotstart, Arcforce and Antistick are standard.

The integrated water cooler is housed in a drawer at the bottom of the machine, so it can be pulled out for easy servicing.

HighPULSE touch power on the move.

Can be fitted with an optional water cooler.

The welding machine can also be mounted on a trolley with drawers.
Merkle HighPULSE touch 280/350 K. - versatile for any application!
The welding machine is a good choice for workshops, assembly, repairs and production tasks requiring lower power. At 33/36 kg, it is lightweight and easy to move. It can also be used in hard-to-reach places. It can even be suspended using our suspension system (optional). All functions are available directly at the work area; only the power cable needs to be connected.

Perfect for welding at higher currents or for extended periods.

Compact and easily accessible.

Easy and safe to move
MERKLE HighPULSE touch 400/450 KW - with side-mounted wire feeder!
When developing the Merkle HighPulse touch 400/450 KW, we placed great emphasis on a compact yet simple design. We also kept this in mind when positioning the wire feeder. The 4-roll DV-26 wire feeder and wire spool are easily accessible by opening the side of the machine.

Merkle TEDAC® system
Perfect control with Merkle TEDAC® torches.

It can significantly extend the welding reach, particularly when working with aluminium, and in some cases TEDAC® control can also be indispensable.

Lift-start TIG function with continuously adjustable upslope and downslope, and gas pre-flow and post-flow.


Mobile version with 4 castors.

Fold-out handle, 2 x 4 rubber feet on the bottom and side.

Electrically insulated suspension device (optional)

Asymmetrical mounting point extends the machine's reach (optional)

Horizontal positioning as standard.

Vertical positioning can be achieved in seconds.
