WORK
Welder controls are simple and
clearly marked. The output voltage
is controlled by a twelve position
tap switch, providing 4 TIG and 8
MIG voltage selections. Wire feed
speed is controlled by the wire
speed potentiometer.

GLOBULAR TRANSFER
Globular transfer occurs at the
intermediate range of 22 to 24 arc
volts, depending on wire size. As
the name implies, the transfer
takes place in the form of irregu-
larly shaped globules. Globular
transfer is useful in cases where a
lower heat input than that of true
spray is required.
SPRAY TRANSFER
Spray transfer occurs at 22 to 32
arc volts, depending on wire size.
The length of the arc is held
constant by the voltage available.
The higher voltage and current
causes the electrode wire to melt
off before touching the workpiece.
The molten metal crosses the gap to
the workpiece in a spray form.
Spray transfer is used in the down-
hand position and provides higher
deposition rates than short arc
transfer or globular transfer.
DESCRIPTION
The PBE250 consists of a combina-
tion MIG welding power source and
wire feed unit, a MIG torch with 10
foot cable, a ten foot work cable
with clamp, a twenty foot power
input cable, a gas regulator -
flowmeter, a torch accessory kit,
and a built-in cylinder rack and
industrial wheel kit.
