LANGUAGeS
From the home screen press the
scroll down button 8 times (or the
scroll up button once) to access the Language Screen. This allows the unit to
display the screens in English, Spanish or French. The upper rotary knob selects
which language to use on the screens. Once a language is selected all menus will
be displayed in that language.
If the last row of the Maintenance Screen displays the à lock symbol the feature
can not be reset with out entering the unlocking code (See Code Section for
detail on entering the code).
AUTOMATIC SAfeTY ShUTDOWN
This welder includes an Automatic Safety Shutdown. There are two ways the safety shutdown can be activated.
Thermal Protection
There are 2 levels of thermal protection. When the power source detects that it is getting warm, the unit will
activate the cooling fan. The fan will operate until the temperature of the power source has dropped below the cooling
threshold.
The second stage of thermal protection will shut the unit down in the event that the fan can not cool the power supply
adequately. The unit will not power up until it has returned to a safe operating temperature. The unit can go into thermal
overload for two reasons. The first reason would be a malfunction in the unit itself. The second reason would be that the
duty cycle has been exceeded.
When the unit cools down the thermal overload protection will automatically reset. After the thermal overload has reset
the unit will function normally.
Shorted Weld SCR
If the microprocessor detects voltage at the output terminals when the unit is not welding it will shut the unit off.
This means that one of the six main switching devices has shorted. If this condition occurs, the unit could potentially weld
without triggering a weld tool. This is a potentially dangerous condition. The microprocessor detects this condition and
shuts the welder down. The unit can be restarted, but will shut down almost immediately once this condition is detected.
The unit must be repaired.
GeNeRAL INfORMATION
The system microprocessor automatically detects and identifies each installed module. Once detected the system
is ready to use the optional feature. All optional features are accessed by pressing the control button(s) on the optional
feature.
When working on a multi-weld tool unit, all setting changes are made to the active weld tool. To make a weld tool the active
weld tool, press the weld tool control button for that weld tool (or air trigger the weld tool you wish to adjust) i.e. if you
want to recall/review/change settings for Weld tool 3, press the weld tool 3 button on the weld tool control panel or pull
the trigger on Weld tool 3 while weld tool 3 is in the air. When a unit is set up for multiple weld tools, it keeps separate
settings for each weld tool. Only settings for the active weld tool can be changed.
