ARC-HOT ONE CVPS POWER SUPPLY

Hot wire Gas Tungsten Arc Welding (GTAW) is a variation on standard GTAW
A second power supply is connected between a wire contact tube (similar to a GMA torch) and the work piece
The wire is fed into the weld puddle immediately behind the arc
Normally a AC constant voltage power supply is used. This minimizes magnetic interference (arc blow) of the main GTA arc
The hot wire power supply electrically resistance heats the wire before it reaches the puddle
This preheating allows higher deposition rates and/or lower dilution rates
Deposition rates up to 16 pounds per hour have been achieved in the flat position. 3 pounds per hour are typical in the 2G (horizontal) position
At ARC Specialties we have recently developed a solid state hot wire power supply
HOT-ONE is a compact unit measuring 12 x 15 x 16” weighing 95 pounds
Input power is 230/480 VAC single phase, 60 Hz
Output is 0-15 VAC constant voltage
Rated at 150 amps 100% duty cycle
Output voltage is controlled using an external 0-10 VDC signal or an optional front panel knob

Plasma Transferred ARC Welding and Stereolithography applications
Optimized for feeding problem powders such as Titanium\Typical feed range from 1/2 ounce per minute to 16 pounds per hour
Hopper sizes up to 70 pounds
Machined from a single billet
Unique dual bearing roller system for precise alignment & support of the metering wheel
Precision jack screws for wheel gap setting and adjustment
Precise feeding holds weld tolerances to thousandths of an inch
Gas feed for blanketing powder and pressurized for feed for longer horizontal applications
Option: variable speed motor feeds from ounces per minute to pounds per hour

Powered by a standard 120 VAC outlet
Large, bright LED display for current feed rate
Toggle switch for feeder speed controlled by manual pot setting or by a remote input from an external system
