K225 SUBMERGED
ARC TWINARC KIT
The Twinarc kit provides for the feeding of
two 5/64, 3/32, or 1/8 in. (1.98, 2.38, or
3.18 mm) solid wires through a single wire
feeder. The electrode wire must be the
same size. The assembly includes a wire
reel, insulated reel mounting bracket, wire
straightener, dual wire guides, nozzle, and
contact block. Installation, operating, and
maintenance instructions are shipped with
each kit, are contained in the IM305 manual,
and can be ordered as Sec. T2.5.3 K225.
K238 HIGH FREQUENCY UNIT
This unit supplies high frequency to the
welding leads for more positive starts, which
may be required for certain difficult starting
applications. Factory-installed insulation is
required. Instructions are shipped with each
unit. Installation instructions are contained
in the IM305 manual and can be ordered as
Sec. T2.5.8.
K239 TWINARC KIT FOR
INNERSHIELD
®
ELECTRODES
This kit provides for welding with two
Innershield electrodes. Two 3/32 in.
(2.38 mm) flux-cored electrodes are fed
through a single wire feeder. Both wires
must be the same size. The K239 kit
includes the nozzle equipped for water
cooling, drive rolls, drive roll locating collar,
idle roll assembly, ingoing and outgoing
guide tubes, wire straightener, wire reel, and
wire reel mounting shaft and insulation.
Instructions are included in the kit, are
contained in the IM305 manual, and can
also be ordered as Sec. T2.5.3 K239.
K278 SPREADARC
TM
The primary application for this accessory is
for hardfacing buildup using a Twinarc
nozzle. The combination “Spreadarc-
Twinarc” covers large areas quickly with
smooth beads of minimum admixture with
the base metal. Flux cored electrode, open
arc, and submerged arc procedures can be
used. Instructions are shipped with the kit,
are contained in the IM305 manual, and can
also be ordered as Sec. T2.5.6.
K281 SOLID WIRE
STRAIGHTENER FOR
TINY TWINARC
This wire straightener will straighten 0.045
through 3/32 in. (1.14 through 2.38 mm) wire
diameters. It is recommended for welding
procedures requiring long stickout and
where wire position accuracy is essential.
Instructions are shipped with the kit, are
contained in the IM305 manual, and can be
ordered as Sec. T2.5.5.
K285 CONCENTRIC FLUX CONE
The concentric flux cone was designed to
fit on the K148 Contact Nozzle alone, the
K148 Contact Nozzle with a K149 Linc-Fill
Long Stickout Extension, the K129
Submerged Arc Small Wire Twinarc, and
the K391 nozzles. (The maximum electrical
stickout when using the K149 Linc-Fill Long
Stickout Extension will be 4 in. [101.6 mm.]).
Use of this attachment results in the flux
being fed concentrically around the
electrodes. Installation, operating, and
maintenance instructions are shipped with
each kit, are contained in the IM305 manual,
and can be ordered as Sec. T2.2.8 K285.
K310 FLUX SCREEN
Useful for any submerged arc equipment. It
removes foreign magnetic particles from
reused submerged arc welding flux.
Operating instructions are included in the kit.
K325 TC-3 TRAVEL CARRIAGE
The K325 Travel Carriage carries the control
box and wire drive head, in either direction,
on a beam of suitable length and
mechanical specifications. Two models are
available: Standard and High Capacity.
