Tandem MIG Dual Wire GMAW

Tandem MIG™ 800 Amp Welding Torch

AUTOMATED SOLUTIONS

The Lincoln Tandem MIG 800 Amp Welding Torch is designed for medium duty robotic and

hard automation applications. The streamline configuration with extended gooseneck profile

is ideal for robotic applications that require reaching welding joints with restricted access.

The lightweight high strength machined aluminum torch construction provides precise wire

placement that can be used on 5 kg load capacity and larger robot arms. The torch features

a heavy-duty brass water-cooled gas nozzle, designed to minimize spatter build-up and

provide extended contact tip life.

locations.

• 22 degree goosenecks provide positive wire contact at the

contact tip.

• Two process derived contact tip spacing and angularity options.

• Large contact tip to diffuser seating area for cooler contact tip

operation.

• Separate routing of air blast hose provides a nozzle cleaning

option without compromising shielding gas supply lines.

SYSTEM RECOMMENDATIONS

www.lincolnelectric.com

Recommended Wire Packaging:

The 22 degree bend in the gooseneck design provides positive wire

delivery to the contact tip for good electrical transfer of welding current.

Bulk wire packing in Accu-Trak™ drums, boxes or Speed-Feed reels is

recommended. It is also recommended to install a K1733-1 wire

straightener at the wire feeder. The addition of a wire straightener is to

adjust for irregular conditioning of the wire during long conduit runs

between bulk wire source and the wire feeder.

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. The reamer 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 is designed to operate with

one water cooler. The cooler is used

to supply cooling water to the torch’s

gas nozzle. Once cooling water is

applied, the brass nozzle is designed

to pull heat from the contact tips and

provide a cool nozzle surface that will

limit spatter build-up. Recommended

AD1013-3 cooling system includes:

Cool-Arc 40 water cooler, Magnum

Flow Sensor and 25 ft each of water

delivery and return hoses.

The 800 amp Tandem MIG torch is supplied with Power Feed 10 Robotic Wire Feeder

compatible cable ends. The cable assemblies plug directly into the feeder power block,

(with K1506-1 gun connector installed.) Gas is delivered to each side of the torch through a

short hose extending from associated wire feeder gas outlet fitting.

Diffuser and contact tips:

High current capacity taper lock contact tips and diffuser

As standard, the Tandem MIG 800 Amp Welding Torch is supplied with Taper Lock

Diffusers (S22693-207) and Taper Lock Contact Tips. Diffusers are designed to provide a

larger seating surface for the contact tips. The enlarged seating surface provides better

current carrying capacity over conventional diffuser designs. Better current carrying

capacity means less heating of the contact tips, longer tip wear and fewer tip changes.

The diffuser design is complimented with a taper lock contact tip design providing a

generous contact mating surface, fewer screw threads and dual thread starting points to

speed tip replacement time.

Conventional heavy duty contact tips and diffuser

Industry standard contact tips and diffuser design are available for end users that have

established a plant standard. The diffuser design is unique to the Tandem MIG torch,

however the contact tip can be used on compatible semiautomatic welding torches.
