***
* Cut capacity speeds are not necessarily maximum speeds�
They are the speeds that must be achieved to be rated at that
thickness�
** Maximum cut speeds are the results of intensive laboratory
testing� Actual cutting speeds may vary based on different cutting
applications�
Cut charts are a guide for mechanized cutting, individual systems
can be “fine tuned” to achieve optimum cut quality�
*** Unshielded configuration, as Thermacut might offers so called
unshielded consumables that could be used for mechanised
cutting and for handheld cutting outside CE conformity country’s
be aware of some facts: If mechanised cutting; Increase the
torch to work distance when mechanised cutting, as thumbs rule
increase the TTWD (Torch To Work Distance) distance by min�
of 1mm over the recommended shielded version� Increase the
piercing height about 1�2 mm for material thickness up to 8mm
and over 8mm about 1�5 mm� Adjust the cutting speed as thumbs
rule by reduction of 10% versus the shield configuration� Adjust
the AVC settings to new distance and speed� (Normally reduce
the AVC setting by 5 – 7 Volts�) Thermacut NOT recommends
and or promotes operating handheld cutting when not using the
shielded consumables�
