the current in amperes and
Connect the TIG torch to the negative terminal and the work clamp to the positive.
In this machine, arc striking is done using the LIFt ARC method, (touch and lift). This type of ignition
does not create electromagnetic interference, unlike HF (high frequency) ignition, so it can be used in
areas where electromagnetic emission is not allowed, such as airports, operating rooms, etc.
1. Turn on the machine and open the gas bottle valve, adjusting the volume depending on the work
to be done.
2. Open the flow regulator
3. To start welding you must touch the tip of the tungsten electrode to the work piece

before it cools down. Therefore, the torch should be held at this point after the arc is
extinguished.
