SECTION 1 DESCRIPTION
1.1 General
The Ultra Pulse 450i pendant is designed to provide
simple to use, high quality, synergic pulsed Mig welding
when used with an SVI 450i or MTS 450i inverter power
source and a Mig 4HD or MIGhty 4HD wire feeder.
Synergic pulsed Mig welding means that pulse param-
eters (such as pulse height, pulse width, background
current and pulse frequency) are automatically adjusted
by the Ultra Pulse 450i pendant as you change wire feed
speed.
The Ultra Pulse 450i pendant also provides a PULSE
ARC TRIM dial that enables the operator to fine tune the
pulse arc by adjusting the arc length. The operator can
change to standard welding by simply moving the PULSE
/STANDARD switch to the STANDARD position. The
system can then be used for non-pulsed Mig (GMAW),
Tig (GTAW) or stick electrode welding (SMAW) by
connecting the appropriate welding torch or electrode
holder.
SECTION 2 INSTALLATION
back to the pendant and power source. Therefore, it is
important that the wire feeder be set-up properly. There
are three possible configurations for the wire feeder:
a. Wire feeder
without
a digital meter kit.
b. Wire feeder
with
a digital meter kit.
c. Older wire feeder
without
installed connectors.
Follow the procedure below (a,b or c) that best describes
your wire feeder.
a. Procedure for Wire Feeder Without Digital Meter
Kit Installed
Remove the wire feeder sheet metal cover and
locate the spare violet wire in the multi-conduc-
tor cable exiting the rear panel of the Mig 4HD
feeder. The violet wire will have a single in-line
connector. Connect the mating connector of the
supplied single wire harness to the mating violet
wire and the plug end to the P3 receptacle on the
Mig 4HD main P/C board.
b. Procedure for Wire Feeder With Digital Meter
Kit Installed
Remove the wire feeder sheet metal cover and
locate the spare violet wire in the multi-conduc-
tor cable exiting the rear panel of the Mig 4HD
feeder. The violet wire will have a single in-line
connector. Connect the spare mating connec-
tor (P1-3) of the five wire harness supplied with
the Digital Meter kit to the violet wire of the multi-
conductor cable. Connect the Digital Meter wire
harness between P3 of the Main P/C board and
P1 of the Digital Meter board.
2.1 General
ELECTRIC SHOCK CAN KILL! Make sure that all
primary input power to the power source and wire
feeder has been disconnected at the wall (line) dis-
connect switch or circuit breaker before making the
following connections.
The following instructions are intended to supplement
the manuals supplied with the wire feeder and power
source. Be sure to follow all installation, operation and
safety information provided by these manuals.
2.2 Cable Connections
Refer to Figure 2.
The Ultra Pulse 450i pendant is supplied with a 8-ft (2.4
m) control cable with a 19 pin male amphenol style
connector and a 19 pin female amphenol receptacle.
a. Connect the 19 pin plug to the mating receptacle
on the SVI 450i or MTS 450i power source.
b. Connect the 19 pin male amphenol plug from the
wire feeder to the mating receptacle on the Ultra
Pulse pendant.
c. Be sure that the secondary output connections
(welding cables) are connected so that the posi-
tive cable goes to the wire feeder and the nega-
tive cable goes to the work piece.
2.3 Wire Feeder Set-Up
In order for the synergic pulsed Mig operation to function
properly, the wire feeder must provide the proper signals
