The ICE-55C torch includes a drag shield that attaches to the cup and holds the tip 1/8 in (3.2 mm) off the workpiece. This permits the operator to drag the torch on the work piece while cutting at full output, which increases operator comfort and makes template cutting easier.

Auto-Line

™

automatically links the

Spectrum

2050 to any primary input voltage from 208 to 575 V, single- or three-phase, 50 or 60 Hz.

A standard feature, the pilot arc switch in expanded metal mode allows operator to cut grates, chain link fence, and other perforated metals without retriggering the gun.

Consumables storage compartment

provides convenient access to consumables and parts.

Can be powered by any Miller engine drive with generator power

(e.g. Bobcat

™

) or equivalent competitive equipment. See page 3 for engine drive compatibility and recommended settings.

Postflow cooling circuit cools consumables and torch with postflow air after you release the trigger. This feature extends life of the torch and consumables.

Starts without high-frequency so it will not interfere with or damage controls or computers.

Built-in gas/air filter/regulator is housed inside the power source for protection from transportation damage. A standard air connection is also provided on the back panel for easy gas or air hookup.

Wind Tunnel Technology

™

prevents abrasive dust and particles from damaging internal components. Also, the

Fan-On-Demand

™

cooling system only operates when needed. In dirty or dusty environments, this feature reduces the amount of airborne dust/dirt pulled through the unit.

Portable, easy-to-carry unit weighs only 86 lb (39 kg).

Power source is warranted for 3 years, parts and labor.

ICE torch is warranted for 1 year, parts and labor.

ICE-55C torch offers improved plasma flow characteristics for increased cutting speeds and longer consumable set life.

To determine the maximum rated cutting thick ness of mild steel, follow the line from the 10 IPM (inches per minute) point on the cutting chart. The point at which this line intersects the cutting curve determines the maximum recommended production cutting thickness of the unit.

Note: The rating is based on 10 IPM because this is the minimum speed at which the operator achieves a smooth, steady cut when using a hand-held torch.

Note: Recommended maximum piercing capacity for hand-held applications is 7/16 in (11 mm). Maximum Sever cut of 1-1/8 in (28.6 mm) a 3 IPM For aluminum and other metals with high thermal conductivity, cutting capabilities will be derated as much as 30%.

Maximum Sever cut of

1-1/8 in (28.6 mm) at 3 IPM

Rated cut capacity is based on traveling approximately 10 inches per minute to achieve a steady, precise cut. This is the key rating that should meet or exceed your typical cutting thickness requirements.
