Mounting the Torch
Bend-Tech recommends mounting the Torch wand so the edge of the ceramic body closest
Torch lower than this could lead to Torch collision. Mounting the Torch higher could cause
problems with the Torch developing an arc on the material when the Toolhead reaches certain
parts of its travel.
Routing the Torch Lead
The Torch lead carries a high current load and can cause interference if routed close to other
electrical cords and connections on the machine. It is important to route the Torch lead away
from other cords on the machine. It is critical to route the Torch lead clear of the Ethernet
cable. The Torch lead can cause connectivity issues if routed close to the Ethernet cable.
Some models of the Dragon A150 are equipped with cable loops pre-installed for the purpose
of securing the Torch lead.

The Customer should ensure the Torch lead is secured so it is clear of the cables at
the top of the Toolhead. It is recommended that the Torch lead be secured so it loops
up above the components at the top of the Toolhead.
The Operator can verify Torch height by manually pushing down on the Engraver and
observing if the Engraver engaged height is the same as Torch height.
