no arcing.
Move gun further from
surface.
Adjust the regulator on the
tool to the maximum setting.
Adjust the compressor
regulator to tool maximum
of 45 PSI. NOTE: Air hoses
may cause up to 15 PSI loss
in pressure, so you may need
to set a higher compressor
output to maintain the
required pressure at the tool.
