Piercing
Rest the contact drag shield on the
work piece at 45° angle
Press the trigger-switch on the torch handle.
Air will flow for one second before the pilot arc strikes.
After cutting arc starts, slowly and in one smooth movement,
straighten torch back up until 90° angle to plate.
Start moving torch across plate when observing that the arc
penetrates.
Circle cutting guide (optional accessory)
The wheeled wagon in the circle cutting set should be used when
cutting on uneven surfaces where it is difficult to use the drag
shield.
1. Pull off the drag shield
2. Insert the torch to a position where the distance from nozzle
tip to work piece is 3-4mm
3. Tighten the allen screw on the inner ring.
4. Tighten the allen screw on the outer ring with the wheels
axis at 90° to the torch handle
For cutting circles the allen screw in point 4 must be loosened to
allow the torch to rotate in the wagon.
The circle cutting bar is screwed into the wheel centre, and the
centre tap is fastened at the correct radius.

groove.
5 Groove depth and width is adjusted by weaving and torch angle.
