CUTTING MODE CHOICE
Choose the cutting mode by using the selection button
Cutting / gouging of solid sheets
This is the most commonly used mode. Pull the trigger to create the arc, and release it to stop or ""unblock"" (the arc stops by
itself). To restart the work, release the trigger and pull it again.
Cutting / gouging of perforated sheets
This mode follows the same principles as the previous one except when ""unblocking"": the arc will start again if the trigger
while the trigger is pulled. This mode is more comfortable to use, as it avoids constant pull and release of the trigger.
Cutting / gouging long pieces of metal
This mode allows the operator to release the trigger during the cut, which will continue until the trigger is pressed again or
""unblocking"". This mode prevents fatigue and keeps your hand a little further away from the cutting area.
CUTTING SEQUENCE
1- When the trigger is pressed, the pilot-arc starts. It is a low power arc generated between the electrode and the nozzle and it allows the arc to
start on the piece of metal to be cut.
2- When the pilot-arc touches the plate, the plasma cutter detects the start. The arc then flows between the electrode and the plate, and the
machine increases the current up to the value set by the operator.
3- At the end of cutting (trigger release or unblocking), the arc stops, the air continues to come out for several dozens of seconds to cool the torch
and consumables down.
MANUAL CUT FROM THE EDGE OF THE WORKPIECE:
The earth clamp attached to the metal piece, hold the torch pad in perpendicular
1
position (90°) to the end of the workpiece.
Pull the trigger of the torch to prime the arc until the torch has completely pass
2
through the part.
Once the cutting has started, drag the pad slightly on the metal sheet to continue
3
cutting. Try to maintain a regular rhythm.
