• For TIG welding, the negative welding terminal (-) is used for the welding torch and the
positive welding terminal (+) is used for the return cable.
• For MMA welding, the welding cable can be connected to the positive welding terminal
(+) or negative welding terminal (-), depending on the type of electrode used. The
connection polarity is stated on the electrode packaging.
5.4
Turning the power on/off
Turn on the power by turning the switch to the “ON” (I) position.
Turn the unit off by turning the switch to the “O” position.
Whether the power supply is interrupted or the power source is switched off in the normal
manner, weld programs are stored so that they are available the next time the unit is started.
CAUTION!
Do not turn off the power source during welding (with load).
5.5
Fan control
The
Rogue ES 150i, ES 180i
is fitted with a fan as needed feature. Fan as needed
automatically switches the cooling fan off when it is not required. This has two main
advantages; (1) to minimize power consumption, and (2) to minimize the amount of
contaminants such as dust that are drawn into the power source.
Note that the fan will only operate when required for cooling purposes and will automatically
switch off when not required.
5.6
Thermal protection
The power source includes thermal protection against overheating. When
overheating occurs the welding is stopped and overheating indicator on the
panel will be lit and an error message shows in the display. The protection is
automatically reset when the temperature has been sufficiently reduced.
5.7
Functions and symbols
MMA welding
MMA welding may also be referred to as welding with coated electrodes. Striking
the arc melts the electrode, and its coating forms protective slag.
For MMA welding the power source shall be supplemented with:
• welding cable with electrode holder
• return cable with clamp
Arc force
The arc force function determines how the current changes in response to
variations in arc length during welding. Use a low value of arc force to get a calm
arc with little spatter and use a high value to get a hot and digging arc.
Arc force only applies to MMA welding.
