GENERAL DESCRIPTION
The Square Wave TIG 355 is a constant current, single range square wave AC/DC TIG (GTAW) arc welding power source with
The Square Wave TIG 355 includes advanced features such as
RECOMMENDED PROCESSES
The Square Wave TIG 355 is recommended for TIG (GTAW) and stick (SMAW) welding processes within its output capability of 2 to 400 amps on both AC and DC polarity. It is compatible with all Magnum TIG acces- sories as well as many industry standard TIG torches, hoses, and water coolers. (See the Accessories sec- tion of this manual.)
OPERATIONAL FEATURES AND CONTROLS
The following operational controls are standard on the Square Wave TIG 355: Local/Remote current control switch, Stick/TIG mode selection switch, TIG 2- Step/TIG
The following additional features are also standard: Digital ammeter selectable for either volts or amps; Status Indicator LEDs for gas and water, high frequen- cy, arc established, start, peak, background, crater fill.
DESIGN FEATURES AND ADVANTAGES
•Designed to NEMA
•Single output range of
•Solid State Output Contactor: no noise, no parts to wear.
•Digital Ammeter and Voltmeter for precise readings from
•Welding current limit can be preset from
•Auto Balance™ circuitry automatically provides the proper amount of cleaning and penetration when AC TIG welding. Manual AC wave balance adjust- ment is also possible.
•
•Spot control for
•TIG Pulser with On/Off selection, and Pulses Per Second adjustment. Background current and duty cycle are automatically adjusted according to the peak welding current.
•Crater Fill control for current
•Adjustable preflow time from 0 to 10 seconds. Preflow time is eliminated if welding restarts during gas afterflow of previous weld. This avoids unnec- essary delays when making repeated welds.
•Adjustable afterflow time control.
•Locate/Remote current selection.
•Stick/TIG selection.
•Arc Force control of added current when electrode shorts to the work in stick mode.
•Continuous/Start/Off High Frequency selection.
•DC+/AC/DC- Polarity switch.
•Power Factor Correction for lower input currents and smaller input wire sizes.
•Remote Receptacle for Amptrol™ or Arc Start switch.
•Low Voltage Arc Start switch circuit (24 VAC) for maximum operator safety.
•Gas and optional water valves: Inlet and outlet fit- tings conform to Compressed Gas Association (CGA) standards.
