WP-500 General
Operating Instructions
The PROFAX Welding Positioner is designed for light loads, with a maximum load of 500 lbs. when the table is in a vertical position and 900
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 500 lbs. with the table in the vertical position or 900 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 6” 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 300 amps. Do not attempt to
run higher than 300 amps through the grounding brush. Welding currents greater than 300 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.
