4.4 CHOOSING THE WELD MODE

The Hybrid Spot is a multi-functional resistance spot welder. It is equipped with a four weld cable
system for your convenience. Two of the weld cables are connected to the Double-Sided Spot Gun and
the other two are connected to the Single-Sided Spot Gun.
The unit has 3 possible power settings in each mode: Low, Medium, and High. These settings will select
the number of batteries used to produce the weld, as shown in the table below:
No action is necessary to switch between Single and Double-Sided modes. Simply push the trigger on
the gun you want to use, and the welder will automatically select the right number of batteries. Note
that in Single-Sided mode, the "Low" power setting should be used for most applications, otherwise
excessive heating and burn-through can result.
When fewer than 4 batteries are used for a weld, the PHS-101 uses battery management software to
determine which batteries have the highest remaining charge so that the strongest possible weld is
delivered every time. This balancing software also ensures that the batteries are used evenly, so that no
single battery wears down faster than the others.

4.5 SETTING THE PNEUMATIC AIR PRESSURE

Pneumatic air is used for:
- forcing the spot gun to close and open
- cooling the welding cables that are connected to the spot gun.
The air pressure is regulated with the air regulator, and the set pressure is indicated on the pressure
gauge. Default pressure is 90 PSI.
Change the air pressure as follows:
1. Unlock the pressure regulator by pulling on the adjustor knob till it snaps into the unlocked position.
2. Turn the pressure regulator knob clockwise to increase or counter-clockwise to decrease the air
pressure.
3. Lock the pressure regulator by pushing the knob into the lock position.

4.6 USER INTERFACE

The PHS-101 uses a Weld Control Button to scroll through menu options on the LCD and to change
settings. Rotating the Weld Control Button back and forth will move the
LCD. To use the selected menu option, press the Weld Control Button once (do not hold). If the chosen
selection is a numeric setting, the
