2.05 General Information
The HMC-410 is an automatic/semiautomatic control
panel capable of precisely controlling a power source
(welding machine), wire feed motor, gas valve solenoid,
and if present an automatic fixture. The HMC-410 can be
controlled from the front panel or remotely through an
optional remote pendant assembly, optional auxiliary
interface cable, or optional robotic interface (see HMC-
410 Accessories And Option Descriptions chapter for
more details). The functional capability of the HMC-410
can be changed to meet more specific customer
applications by changing the system’s software. The HMC-
410 divides the weld process (schedule) into ready,
preflow, run in, weld, crater fill, burnback, post-flow, and
recycle segments. The user can program the appropriate
parameters (time, voltage, and wire feed speed) into each
segment. The HMC- 410 can store up to 10 weld schedules
in nonvolatile memory (schedules are saved even with
input power removed)
The HMC-410 comes with an abundance of standard
features which include:
• an on/off rocker switch with built-in circuit breaker
for total system protection
• a weld/program key switch for operator lockout
• an inch switch
• a purge switch
• a test mode switch allowing a run through of a
programmed weld sequence setup without welding
• continuous-turn encoders for precise parameter
input
• numerous LED displays for visual indication of
parameters and modes
• a special soft switch screen allowing custom
programming of system capabilities
• software upgrades to tailor the performance and
capability of the system
• a self-diagnostics routine to aid in servicing
• a remote pendant amphenol input
• an auxiliary amphenol input for connection to PLC
controllers or other fixturing
• a tachometer feedback control loop for precise wire
feed speed control
• onboard fuses for system protection
• a ground fault circuit to protect the operator and
equipment from welding current flowing through
the ground system of the control panel
• a solid state circuit providing current limit to the
wire feed motor
• a solid state dynamic brake.
The HMC-410 has been designed to comply with CSA
NRTL/C, NEMA EW 3, and CE (IEC974-5) standards.
