CONNECTABLE PLASMA CUTTER 40A
• If holes are drilled or if the part is to be cut from the centre, the torch must be
inclined and then slowly straightened to prevent the molten metal from spreading
over the part. (4).
• This operation must be carried out with a material thickness greater than 2 mm.
• If you have to cut near corners or recesses (5), it is recommended to use
electrodes and elongated nozzles.
N.B.: Avoid holding the pilot arc on unnecessarily to avoid consuming electrodes
and nozzles.
When you have fi nished working, switch off the machine and hang
the torch on the hook provided.
CUTTING TROUBLE
1) Insuffi cient penetration
Causes :
• a speed too high. Always ensure that the arc passes through the part to be cut
and that it is not tilted forward by more than 10 / 15° (6). This prevents wear on
the nozzle (7) and burning of the nozzle holder (8).
• excessive thickness of the part to be cut
• the working pliers (H) are not in proper electrical contact with the part to be
cut
• worn nozzle and electrode
• cutting current too low.
N.B.: When the device does not pass completely, it means that the nozzle must
be blocked by chips.
2) Cutting arc switches off
Causes :
• worn nozzle, electrode or diff user (B)
• too high air pressure
• supply voltage too low
3) Tilted cutting
When the cutout is tilted (9), turn off the unit, loosen the nozzle holder and turn
the nozzle a quarter turn, then lock and try again.
Repeat the operation until the cut is straight (10).
4) Excessive wear of consumable parts
Causes :
• air pressure too low compared to the recommended air pressure
• excessive esses on the end of the nozzle holder.
