PT-200A & B
Weight Capacity
Q: What are the weight ratings?
- 100A Series: 200 lb capacity
- 200A Series: 440 lb capacity
Q: Why is vertical capacity lower?
A: Vertical capacity is reduced because the load places direct downward force on the bearings. These machines are primarily designed for horizontal use.
Country of Origin & Warranty
Q: Where are the welding positioners made?
A: Taiwan
Q: What is the warranty?
A: 1-year warranty
Replacement Parts
Q: Are replacement parts readily available?
A: Yes. These machines use standard industrial components, and replacement parts are widely available.
Grounding the Positioner
Q: How do you properly ground the positioner?
A: A spring-loaded brass pin or block contacts the backside of the turntable.
Dirty or contaminated surfaces will prevent proper grounding and may cause machine failure.
Arc-Zone recommends using emery cloth to clean or rough the surface for solid electrical contact.
Foot Control
Q: Does the machine include a foot control?
A: Yes. The standard setup includes an on/off foot control.
Variable speed foot control is available as an upgrade:
- CB-001V: Variable speed control
- CB-001VF: Dual control option
Chuck Size
Q: What size chuck is included?
A: 10" OD standard machine tool style chuck
Speed Control & RPM
Q: What are the RPM ranges?
- A Series: 1–15 RPM
- B Series: 0–4 RPM
Q: How is speed controlled?
A: Potentiometer-based control for precise speed adjustment.
Q: Does the foot pedal control speed?
A: No. The foot pedal starts and stops the machine. Speed is set on the control panel.
Motor Type
Q: What type of motor is used?
A: 45-watt DC motor
Range of Motion
Q: Can the machine tilt to 90 degrees?
A: Yes. The table can be tilted for horizontal or flat positioning.
