GENERAL DESCRIPTION
The DH-10 is a modular line of 42VAC 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 selec-
tability 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 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.
This equipment is for industrial use only and it is not intended for
use in residential locations where the electrical power is provided by
the public low-voltage supply system. There can be potential diffi-
culties in residential locations due to conducted as well as radiated
radio-frequency disturbances. The EMC or RF classification of this
equipment is Class A.
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 mounting.
INSTALLATION
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, 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 receptacle. 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.
