- A portable and flexible automatic welding head designed for ship and barge building, spherical storage tank erection, bridge deck installation, beam, girder, or column fabrication, long seams on heavy weldments
- All controls are located on the tractor, eliminating the need to return to the power source for routine procedure changes
- Adjustments to electrode stickout or welding angles and tractor configuration changes can be made quickly and easily
- Requires only simple, routine maintenance for trouble-free, hardworking operation
Controls
- Current and voltage meters for monitoring weld parameters while welding
- 115 VAC control switch
- Inch buttons feed the electrode up and down at fixed inch speed
- Push buttons start and stop the arc and travel
- 115 VAC receptacle provides 120 watts of power for work lights
- Calibrated travel speed control sets speed of travel in inches per minute
- Direction of travel switch sets forward or reverse tractor direction for easy setup
- Travel switch controls the tractor travel for automatic starting and stopping when welding, travel without welding during setup, and travel off
- CC-CV switch is inside control box for selecting between constant current and constant voltage power sources
