The Extra Heavy Duty Flux Recovery Units with Time-proven Performance and Many Exclusive Features

Since the very beginning of submerged arc welding, Arco Wand Recovery Units have proven themselves as a most valuable, in fact, almost essential accessory to the entire sub-arc process. The key word is economy. They save valuable flux, help make better welds and produce all-important saving in man hours. In addition, they are basic to good housekeeping. Recovery units not only make for a neater shop and better working conditions but they also keep abrasive flux away from moving parts on the welding rig. Finally, the units are capable of separating out slag (fused flux) and fines (flux flour) returning only clean reusable flux to the hopper.

Some Unique and Important Features:
AUTOMATIC DUST BAG CLEANING	ARCO WAND UNITS are equipped with a dust bag shaking device which cleans the bags without taking them out of the machine and shaking them, a time consuming and very messy job. This is a most important feature because as the bags become dirty, the suction and thus the pick-up power of the unit is considerably reduced.
VACUUM PRODUCER PROTECTION	Another exclusive feature of the ARCO WAND is the use of a secondary oil bath type air cleaner which prevents any possible damage to the vacuum producer in the event of filter bag failure. This eliminates the possibility of costly down time and expensive replacement parts.
SLOW SPEED	The ARCO WAND has been made for over 70 years and combines super-power with economical operation and long life. Its vacuum is created by a slow speed pump (1000 R.P.M.) and not by a high-speed fan or turbine, resulting in a uniform powerful suction. ARCO WAND units are proportioned for continuous heavy duty service and can be used where ordinary machines are inadequate because insufficient power and light construction fails to provide this sturdiness necessary for severe service. Unlike so-called "heavy duty units" using high speed motors which are subject to quick deterioration from extreme commentator and brush wear, the ARCO WAND is powered with standard general purpose 1750 R.P.M. motors. This makes continuous service possible, and allows us to guarantee these machines for 24 hour a day operation.
HIGH VACUUM	ARCO WAND UNITS PRODUCE THE HIGHEST VACUUM AND HAVE THE HIGHEST RECOVERY RATE PER HORSEPOWER OF ANY UNIT MADE. This high vacuum allows satisfactory operation with long hose lines and high vertical lifts essential for many operations.

DOUBLE TANK PORTABLE
The Double Tank Portable Unit, at right, has all the features of the single tank model above plus some valuable extra features.

First: In connection with certain flux, there is an accumulation of fine dust known as flux flour. This dust can cause pin holes in the weld and it is often necessary to get rid of it. To accomplish this, a primary or extra separator is used as pictured. Unfused flux from the work enters the primary tank and strikes a baffle agitating this dust (fines) which is carried over by suction to the secondary tank where it can be quickly disposed of by emptying the bucket.

Second: The primary tank is equipped with a slag screen which screens out all fused particles. It also has a quick open dump valve which allows the clean reusable flux to be emptied into any convenient container for transfer to the weld hopper.

This machine Is also made in stationary models:
552-S, 882-5, 992-S, 1002-S, 1202-S

SINGLE TANK STATIONARY
The machine pictured at right is intended for mounting overhead and returns screened, usable flux by gravity direct to the hopper on the weld head.

Tank is equipped with a metal screen tray which screens out all fused particles. Quick open valve at bottom of hopper allows very rapid filling of flux hopper. This unit as well as double tank machine pictured on next page can be arranged for continuous operation. That is, simultaneous pick-up and feedback of flux.

Model 8MH—2 H.P.
Model 9MH—3 H.P.

Model 1OMH—5 H.P.
Model 12MH—71/2 H.P.

DOUBLE TANK STATIONARY
Where space or weight factors do not permit mounting the entire machine overhead, the power unit can be placed on the floor and just the tank (primary separator) elevated, as shown on left. This set-up also effects a complete separation of fines (flux flour). Connection between the power unit and the primary separator is made by means of a special flexible rubber hose. This hose may be as long as 50 to 75 feet to permit tank to ride on a traveling fixture. This overhead tank also contains a screen to separate out all fused particles (slag).

This is the type unit usually furnished on the large manipulators and positioners.

The primary separators are more fully described on specification page. They are made in a variety of sizes to fit into any particular application without costly fixtures and high installation costs.
