The Kemppi Kempak 200A is a TIG power source on direct current with HF ignition, gas cooled. The description gives 200 A at a 20% duty cycle and 90 A at a 100% duty cycle. The machine also handles welding with a covered electrode.
What this machine is for
This is a power source for TIG welding on direct current, that is for stainless steel, structural steel, copper and titanium. Aluminium needs alternating current, so you will not set this machine for it. The option of work with a covered electrode adds assembly and repair jobs where a TIG torch is awkward.
The duty cycle splits this machine into two ways of use. You hold the full 200 A for two minutes in ten, so this is a current for short, strong penetration runs and for thicker material. At 90 A you weld with no time limit, and this is the real working current for long welds on a thin wall. HF ignition starts the arc without touching the material, so the tungsten electrode picks up no dirt and the start of the weld comes out clean.
Features and equipment
- TIG on direct current for stainless and structural steel.
- Contactless HF ignition, a clean start without touching the material with the electrode.
- Option of welding with a covered electrode.
- Gas cooling, without a liquid circuit.

What to watch out for
The duty cycle at 200 A is 20%, so for longer welds plan a current closer to 90 A. A gas cooled torch heats up faster than a liquid cooled one, which at the upper settings limits the pace of work more than the power source itself.
The supply cable is only 2 m long, so the socket has to be close to the station or you need an extension lead with the right cross section. The TIG torch is 4 m long, which sets the working radius around the machine. For work you add a cylinder with argon, a regulator, tungsten electrodes and nozzles.
