PRODUCT DESCRIPTION
The SP-255 is a complete semiautomatic constant voltage DC arc welding machine built to meet NEMA specifications. It combines a constant voltage power source and a constant speed wire feeder with a micro- computer-based controller. This forms an intelligent welding system that really puts the automatic in semi- automatic. A touch key entry system with audible feedback, along with a two-line, 32 character alphanu- meric display provide user friendly control of the sys- tem.
Multilingual display capability allows the SP-255 to communicate with the user in any of the following lan- guages: English, German, French, Spanish, or Japanese (Katakana).
RECOMMENDED PROCESSES AND EQUIPMENT
The SP-255 is recommended for GMA welding processes using 10 to 44 lb. (4.5 to 20 kg) 2" (51 mm) I.D. spools or Readi-Reel®coils of .025 through .045 (0.6-1.2 mm) solid steel using CO2, ArCO2, or ArO2 shielding gas, .035" (0.9 mm) stainless steel using ArO2 or HeArCO2 shielding gas, 3/64" (1.2 mm) alu- minum using Ar shielding gas, and .045" (1.2 mm) Outershield® electrodes using CO2 or ArCO2 shielding gas, as well as .035" (0.9 mm) and .045" (1.2 mm) Innershield® self-shielded electrodes.
The SP-255 is factory equipped to feed .035" (0.9
mm)and .045" (1.2 mm) electrodes and includes a 200A, 60% duty cycle rated, 12.5 ft. (3.8 m) GMA gun and cable assembly equipped for these wire sizes. The SP-255 is factory equipped with an adjustable
CO2 and Argon blend flow regulator. A supply of shielding gas is required for GMAW processes.
WELDING CAPABILITY
The SP-255 is rated at 250 amps @ 26 volts at a 35% duty cycle on a ten minute basis. It is capable of high- er duty cycles at lower output currents.
LIMITATIONS
The SP-255 may not operate as designed if powered with a portable or in-plant generator.
