GENERAL DESCRIPTION

The DH-10 is a modular line of 42VAC input dual head 4-roll
wire feeders. A single control with dual procedure presetta-
bility 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 pro-
cedures 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 proce-
dure; 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 forward
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 driven roll
drives housed together in a single combination mounting
and connection box. Gun adapters are available to permit
use with a variety of standard welding guns.
AVAILABLE MODELS:
The DH-10 Wire Feeder system is available configured 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" (50.8mm) O.D. spindle mount-
ing.
INSTALLATION
RECOMMENDED
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,
GMAW 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, +V300-I, V350-
PRO, DC-600, DC-650 PRO and DC-655.
The DC-250, DC-600(Below Code 10500), DC-1000
and the Pulse Power 500 (Non-Pulsed CV mode only)
may also be used with the DH-10 if the optional
K1520-2 115V / 42V Transformer Kit is used.
