• For TIG (GTAW) welding, the negative welding terminal (-) is used for the welding torch
and the positive welding terminal (+) is used for the return cable.
• For Stick (SMAW) 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.

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
MiniArc Rogue 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, welding stops, the overheating indicator on the panel
illuminates, and an error message appears on the display screen. The protection
is automatically reset once the temperature has decreased to a safe level.

Functions and symbols
Stick (SMAW) welding
Stick (SMAW) welding can also be referred to as welding with coated electrodes.
Striking the arc melts the electrode, and its coating forms protective slag.
For Stick (SMAW) welding, the power source must be supplemented with the following:
• Welding cable with electrode holder
• Return cable with clamp
Hot start
Hold the process selection button and the display switches to "HS" (Hot Start).
Current control knob, the display shows 0 or -1 to -10 or 1 to 10 (-10 to +10).
Press the process selection button again and the display switches to AF (Arc
Force).
