2 SPWR − Hot Start
The Millermatic 350P Aluminum is
equipped with a hot start feature. To begin
controlling this feature the user must ac-
cess the system menu by pressing both
the setup button and arc control button at
the same time. Once in the system menu
rotate the left adjustment knob until “ALST”
appears on the left display. There are three
hot start settings: Auto, Off, and On. “Auto”
uses factory default settings for the hot
start parameters. “Off” disables the hot
start feature. “On” allows manual control of
the hot start settings.
When hot start is in the “On” setting the
user must manually configure the hot start
settings as follows. Five presses of the
setup button should bring the user to a
menu indicated by “SPWR” on the left dis-
play. This represents the start power. The
start power is a percentage of the welding
power. Rotate the right adjustment knob
until the power level is as high as desired.
Rotating the left adjustment knob will take
the user to the next menu labeled “STMR”.
This represents the start time in seconds;
use the right adjustment knob to set this
time as desired. During this time the higher
start power will be applied. Rotating the left
adjustment knob again will take the user to
the next menu labeled “STRL”. This rep-
resents the hot start period arc length; use
the right adjustment knob to set the desired
arc length. Rotating the left adjustment
knob one last time brings the user to the fi-
nal menu labeled “RMPT”. This repres-
ents the hot start ramp time in seconds; ro-
tate the right adjustment knob to set this
time as desired. The ramp time is the
transition time from hot start to normal
welding. Pressing the setup button once
more will complete setup of the hot start
parameters.
The two parameters that will have the
largest influence on hot start are the start
power and the start time. These two para-
meters will determine how much heat is
provided and for how long at the beginning
of the weld.
