GENERAL DESCRIPTION

The DH-10 is a modular line of 42 VAC input dual
head 4-roll wire feeders. A single control with dual
procedure presettability of wire feed speed (in IPM or
M/min) and arc voltage for each head is used with a
single DC welding power source.
The DH-10 models have controls providing keypad or
remote selectability of wire drive head, and either of
two procedures preset independently for each head.
The units offer 4 independently selectable gun trigger
modes for each head procedure; cold feed, 2 step and
4-step trigger and spot weld mode.
Also, 4 selectable, presettable timers for each head
procedure; preflow, postflow, burnback and spot weld
time.
Arc starting can be optimized for each head procedure
with 5 selectable wire feed acceleration rates, and
independent control of slower run-in procedure.
A gas purge key is provided, as well as cold feed for-
ward and reverse keys with independently adjustable
forward feed speed setting.
All of these features are selected with a tactile-feel
keypad, and are set independently for each head
using one of two rotating knob encoders, setting levels
are displayed on one of two digital LED displays.
The DH Wire Drive assemblies include two heavy duty
heads with externally changeable gear ratio and 4 dri-
ven roll drives housed together in a single combina-
tion mounting and connection box. Gun adapters are
available to permit use with a variety of standard weld-
ing guns.

AVAILABLE MODELS

The DH-10 Wire Feeder system is available config-
ured in both Bench and Boom models.
Bench Models consists of a DH-10 control and a DH
double header wire drive assembly premounted on a
platform with a dual 2 in. O.D. spindle mounting.
Boom Models consist of a DH-10 control and a choice
of wire drives designed to be mounted separately and
joined by available head to control cable assemblies.
The head to control cable assemblies are available in
two types; one control cable is required for each head:
K1498-"L" Includes a control cable with a 14-pin
ms style connection on each end, and

RECOMMENDED PROCESSES
AND EQUIPMENT
The DH-10 Wire Feeder system is recommended for
use with solid wire gas-metal-arc or CV Submerged
arc processes, as well as cored wire for Outershield
GMA or Innershield processes.
The wire type and size range for the wire drive used,
and gear ratio change selected, are given in the
Specifications.
Recommended power sources are Lincoln Electric
Company constant voltage power sources with 42
VAC auxiliary power and a 14-pin connector recepta-
cle. At the time of printing these include: CV 250,
CV300-I, CV-300, CV400-I, CV-400, CV500-I, DC-
400, CV-655, Invertec V300-PRO, DC-650 PRO and
DC-655.
The DC-250, DC-600, DC-1000 and the Pulse Power
500 (Non-Pulsed CV mode only) may also be used
with the DH-10 if the optional K1520-1 115V / 42V
Transformer Kit is used.
