SAFETY PRECAUTIONS

Read and understand this entire section before operat- ing the machine.

WARNING

ELECTRIC SHOCK can kill.

•Only qualified personnel should perform this installation.

•Turn the input power OFF at the disconnect switch or fuse box.

•Do not touch electrically live parts or electrode with skin or wet cloth- ing.

•Insulate yourself from work and ground.

•Always wear dry insulating gloves.

•Read and follow “Electric Shock Warnings” in the Safety section if weld- ing must be performed under electrical- ly hazardous conditions such as weld- ing in wet areas or on or in the work- piece.

FUMES AND GASES can be dangerous.

• Keep your head out of fumes.

• Use ventilation or exhaust to remove fumes from breathing zone.

WELDING SPARKS

can cause fire or explosion

•Keep flammable material away.

•Do not weld on containers that have held combustibles.

ARC RAYS can burn.

• Wear eye, ear and body protection.

Observe additional Safety Guidelines detailed in the beginning of this manual.

PRODUCT DESCRIPTION

The Precision TIG 275 is part of a new family of indus- trial arc welding power sources providing constant cur- rent, single range square wave AC/DC TIG (GTAW) with new patented (pending) Micro-StartTMTechnology, Presettable Min. and Max. Output controls, and built-in high frequency stabilization for continuous AC TIG and DC TIG starting. It also has AC/DC Stick (SMAW) capability, with adjustable Arc Force availability. A TIG Pulse Panel, Power Factor Capacitors and a Water Solenoid are available as field installed optional kits. Also, a new Undercarriage (with double gas bottle rack) is available for field installation, as well as a new Under-Cooler Cart, which is also included in an avail- able efficiently integrated entire TIG Welding Package with convenient built-in storage provisions for welding equipment and components.

The Precision TIG 275 includes advanced features such as a Digital Meter, Presettable control, Auto BalanceTM, Fan As Needed (F.A.N.) fixed Preflow, vari- able Postflow shielding gas and Timers. In addition, 2- Step/4-Step and Pulse TIG operation with adjustable Downslope Time control are included with an available field installed kit. It also features a Stick stud panel and a universal TIG torch connection box for simultaneous, but separated, electrode outputs.

PIPE THAWING

The Precision TIG 275 is not recommended for pipe thawing.

Duty Cycle

The duty cycle is based upon a 10-minute time period; i.e., for 40% duty cycle, it is 4 minutes welding and 6 minutes idling. If the rated duty cycle is significantly exceeded, the thermostatic protection will shut off the output until the machine cools to a normal operating temperature. (Refer to Specification Section A-1)
