TORCH MAINTENANCE
20
Even if precautions are taken to use only clean air
w
ith a torch, eventually the inside of the torch
becomes coated with residue. This buildup can
affect the arc initiation and the overall cut quality of
t
he torch.
T
he inside of the torch should be cleaned with
electrical contact cleaner using a cotton swab or
soft wet rag. In severe cases, the torch can be
r
emoved from the leads and cleaned more
thoroughly by pouring electrical contact cleaner into
the torch and blowing it through with compressed
a
ir.
D
ry the torch thoroughly before reinstalling.
