Electrode welding
The unit is suitable for welding all commercially available electrodes, whereby the maximum
current corresponds to the maximum output current of the unit. This current can be used to weld
standard electrodes up to 3.25 mm in diameter.
The polarity and current setting for the individual electrodes can be taken from the manufacturer's
specifications of the electrodes. The electrode holder is plugged into the welding current socket
that has the polarity specified for the electrode (see sections 3.3 and 3.4).
All you need to do is select the correct welding current and polarity for the welding task at hand
and the electrode selected for the task. Booster2 does the rest for you. The following functions
automatically ensure good welding work:
3.2.1
Hot start
BOOSTER2 delivers a higher current than the set welding current for approx. ½ second when
starting to weld. The increase is limited by the maximum output current. This ensures good
ignition characteristics and a fast stable arc.
3.2.2
Arc force
BOOSTER2 monitors the welding current and welding voltage during welding. If BOOSTER2
detects that a droplet transition occurs in short circuit, it supplies a higher current than the set
welding current for a short time to quickly release the short circuit. This prevents the BOOSTER2
from dropping out or the electrode sticking during welding.
3.2.3
Anti stick function
If a permanent short-circuit is present during electrode welding, then after 1.0 s the anti-stick
function initiates which limits the output voltage and in turn the current to 5 volts. This prevents the
electrode from burning-out and the permanent short circuit can be easily released by lifting the
electrode.
The control panel is divided into the following zones:
Control lamps for operation and excess temperature
Rotary knob for preselecting the welding current
Label for identifying the BOOSTER2 version B130 / B140 / B150
The symbols on the control panel have the following meanings:
LED lamps
Indicator function
Lights up
Open-circuit voltage at the torch
or electrode holder.
Flashes quickly
The unit is in fault mode
Switch the unit off and back on again
Flashes once per second
The unit is in test mode
Switch the unit off and back on again
Temperature indicator.
The LED (yellow) lights up when the maximum permissible unit temperature is
exceeded. The output current is switched off for as long as this LED is lit. Once
the unit has cooled the LED goes out and welding can commence automatically.
Use CAUTION with the electrode!
