Tandem MIG 900 Amp Welding Torch
[2]
SYSTEM RECOMMENDATIONS
www.lincolnelectric.com
Recommended Wire Packaging:
When selecting wire packaging for wire diameters of .052” and below,
the Tandem MIG 900 Amp Welding Torch should be regarded as a
straight barrel torch, and the wire should have a consistent cast that
promotes good electrical contact at the contact tip. Wire packaging that
provides a consistent cast include spools, coils and Speed-Feed reels.
When using Accu-Trak™ drums or boxes, a combination of two K1733-1
wire straighteners should be used to provide a cast to the wire.
Automatic Torch Cleaning
Internal Air Blast: (robotic and fixed torch applications)
Each torch is supplied with an isolated gas hose and internal air routing
for performing an optional air blast function. As standard, the torch is
configured to receive a high pressure air purge that forces air between
the two diffusers to remove spatter from the internal portion of the
nozzle. Required equipment: high pressure air line capable of supplying
dry air and solenoid.
Torch Reamer: (robotic application)
Increased production efficiency is established when using the M18426-1
Torch Reamer. The reamer is designed to remove unwanted spatter from
the torch nozzle area, eliminating costly downtime
associated with nozzle maintenance. It is equipped
with a single stroke reaming tool that cleans one
side of the torch at a time. The torch is then
indexed to ream the second side. Reamer
comes complete with torch locating plate and
anti-spatter misting station.
Welding Torch Protection:
When mounted on a Fanuc Robot, the
S22693-172 Rigid Mounting Bracket is used
along with Fanuc Collision Guard software.
The rigid torch mounting and software
combination assures repeatable torch
placement and operator safety.
The M17809 Collision Sensor is recommended when using robotic arms
that are not supported with collision sensing software and for fixed torch
mounting associated with hard automation applications.
Water-cooling:
The torch utilizes three water coolers
to maintain cool operation under
extreme welding conditions. Each
electrode power cable is water cooled
to provide extended life of current
carrying cables. A third cooler is used
to provide coolant directly to the
nozzle, further extending contact tip
life and minimizing nozzle
maintenance. Recommended AD1013-
3 cooling system includes: Cool-Arc
40 water cooler, Magnum flow sensor
and 25 ft each of water delivery and
return hoses.
