SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts
such as output terminals or internal
wiring.
• Unless using cold feed feature when
inching with gun trigger, electrode
and drive mechanism are "hot" to
work and ground and could remain
energized several seconds after the
gun trigger is released.
• Turn OFF input power at welding
power source before Control switch
setup or changing drive roll and/or
guide tubes.
• Welding power source must be con-
nected to system ground per the
National Electrical Code or any
applicable local codes.
• Only qualified personnel should
operate this Equipment.
Observe all additional Safety Guidelines detailed
throughout this manual.
DUTY CYCLE
The DH-10 models are rated at 60% duty cycle* for a
maximum current of 600 amps.
* Based on a 10 minute time period (6 minutes on, and 4 minutes off).
DH-10 CONTROL SWITCH SETUP
Initial set up of the DH-10 control for the system com-
ponents being used and for general operator prefer-
ences is done using a pair of 8-pole DIP switches
located inside the DH-10 control box.
Setup DIP Switch Access
1. Shut off the input power to the DH-10 control by
turning off the power at the welding power
source it is connected to.
2. Remove the two screws on the top of the DH-10
control box door and swing the door down to
open.
3. Locate the two 8-pole DIP switches, near the top
left corner of the DH-10 Control P.C. board,
labeled S1 and S2.
4. Switch settings are only programmed during
input power-up restoration.
OPERATION
Setting the DIP Switches
The DIP switches are each labeled with an "ON"
arrow showing the on direction for each of the 8 indi-
vidual switches in each DIP switch (S1 and S2). The
functions of these switches are also labeled and set
as described below:

Wire Drive Head Selection
The DH-10 control is set up for proper presettable
wire feed speed by setting S2 DIP switches (1 to 4) for
Head 1 (left side head) and DIP switches (5 to 8) for
Head 2 (right side head) as appropriate per the follow-
ing examples for the head specification and DH drive
external gear selection being used:
NOTE: Set the proper 4 switches labelled for Head 1
(Left Head) or Head 2 (Right Head) as appropriate for
the way that Head is being used.
