WARNINGS, SAFEGUARDS
&
OPERATING INSTRUCTIONS
MODEL NO: WP-250

ELECTRICAL SHOCK CAN CAUSE INJURY OR DEATH
Electrical equipment must be installed and maintained in accordance with the National Electrical Code, NFPA 70, and all local codes. Maintain Mig-Guns,
Electrode Holders, Tig Torches, Plasma Torches, Work Clamp, Welding Cable, and Welding Machines in good, safe operating condition. Replace worn or
damaged insulation. Do not try to repair or service equipment while the power is still on. Do not service or repair equipment unless you are trained and
qualified to do so. The Electrode and Work (or Ground) circuits are electrically “HOT” when equipment power is on. At no time should you touch the
Electrode and Electrical Ground at the same time with bare skin or wet clothing while the power is on. Insulate yourself from work and ground using dry insulation.
When welding in damp locations make certain the insulation is large enough to cover your full area of physical contact with work and ground. Ground the work (metal
to be welded) to a good electrical earth ground. Keep gas cylinders, chains, wire ropes, hoists, cranes, and elevators away from any par t of the electrical path.
Always be sure the work cable makes a good electrical connection with the metal being welded. Occasionally check all ground connections to determine if they are
mechanically strong and electrically adequate for the current required. The ground connection should be as close as possible to the area being welded. Never touch
electrically “HOT” parts of electrode holders connected to two welding power sources at the same time. The voltage between the two can be the total of the open
circuit voltage of both power sources. When the welding or cutting process requires values of open circuit voltages in alternating current machines higher than 80
volts, and direct current machines higher than 100 volts, adequate insulation or other means must be provided to prevent the operator from making accidental contact
with the high voltage. The use of reliable automatic controls for reducing no load voltage is recommended to reduce shock hazard. When not welding for any
substantial period of time, make certain that no par t of the electrode circuit will accidentally make contact with the work or ground. Never immerse Mig-Guns,
Electrode Holders, Tig Torches, Plasma Torches, or Electrodes in water for cooling.
REFERENCES: See Safety and Operating References A,F,H, and I.
SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH
Keep smoke, fumes, and gases from your breathing zone and the general area. Smoke, fumes, and gases from the welding or cutting process are of
various types and strengths, depending on the kind of base metal being welded on. To ensure your safety, do not breathe these fumes or gases.
Ventilation must be adequate to remove smoke, fumes, and gases during the welding procedure to protect operators and others in the immediate area.
Do not weld in locations where chlorinated hydrocarbon vapors are coming from degreasing, cleaning, or spraying operations. Vapors of chlorinated solvents can form
the toxic gas “phosgene” when exposed to ultraviolet radiation from an electric arc. All solvents, degreasers, and potential sources of these vapors must be removed
from the welding area. Shielding gases used for arc welding can displace air and cause injury or death. Fumes produced by welding or cutting, especially in confined
areas, can cause discomfort and physical harm if inhaled over an extended period of time.
Always provide adequate ventilation in the welding and cutting area to insure breathing air is safe. Use air-supplied respirators if ventilation is not adequate to remove
all fumes and gases. Never Ventilate with Oxygen, because oxygen supports and vigorously accelerates fire.
REFERENCES: See Safety and Operating References A,B,C,H, and I.
HOT PARTS
Hot parts can cause serious burns. The area at and near the work being welded should be handled with proper gloves. Proper clothing should be worn
to prevent spatter or chipped slag from causing burns. Never pick up welded material until it has properly cooled.
REFERENCES: See Safety and Operating References A, B, H, & I.
MOVING PARTS MAY CAUSE INJURY
Have only qualified people remove guards or covers for performing maintenance and troubleshooting. Moving par ts such as cooling fans can maim
fingers or hands and catch loose clothing. Keep tools, hands, hair and clothing away from moving parts. Be sure to reinstall all panels and guards before
operating equipment.
FALLING EQUIPMENT
Lift only the unit to be moved without any running gear, accessories or gas cylinders that may be attached to it. Use equipment of a proper size to lift
and move the unit. Falling equipment can cause personal injury and equipment damage.

WP-250 General
Operating Instructions
The PROFAX Welding Positioner is designed for light loads, with a maximum load of 250 lbs. when the table is in a vertical position and 440
lbs. when it is in the horizontal position.
Loading the Positioner
The positioner may be floor or bench mounted. When mounting the positioner on a bench it is advisable to secure it solidly to the bench to
avoid any possibility of tipping over with a load. See figure 1 for mounting dimensions.
When loading the work piece onto the table it is important that the following guide lines are followed to avoid over turning the positioner and/or
overloading the motor and gear train.
1. Determine the total weight of your work piece including all fixtures, chucks, brackets, etc.
Note: This must not exceed 250 lbs. with the table in the vertical position or 440 lbs. with the table in the horizontal position.
2. Locate the center of gravity of the work piece with any fixtures attached.
3. Mount the work piece to the turn table making sure that the center of gravity is within 4” of the center of the turn table as shown in figure
No. 2.
Warning! Use equipment of a proper size to lift and/or move the weldment onto the positioning table. Falling equipment can cause personal
injury and/or equipment damage.
Welding Cable Ground (Work) Connection
The positioning table is grounded by means of a brush which contacts the underside of the table. See Figure 3. Connection to this is by
means of a welding cable lug. Attach the welding cable lug to a properly sized welding cable and then attach the lug to the brush holder by
means of the bolt provided. Tighten the bolt securely. The brush has a maximum allowable welding current of 200 amps. Do not attempt to
run higher than 200 amps through the grounding brush. Welding currents greater than 200 amps should be grounded directly to the work
piece by means of a proper ground clamp.
Service or repair of this unit must be done by qualified personnel only.
Warning! Before performing any maintenance on this control circuit disconnect the unit from any power supply.
