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 connected
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
