Personal Safety 1. Wearing and using personal safety clothing and safety devices reduce the risk of injury. Wear the following: a. Fire-resistant clothing (Do not wear pants with cuffs, shirts with open pockets, or any clothing that can catch and hold molten metal or sparks.) b. Fire-resistant leather leggings and work boots c. Dry, insulating leather welding gloves d. NIOSH-approved respirator e. Shade 5 or higher welding goggles f. Appropriate head covering to protect head and neck g.
Equipment Setup Safety Safety 1. Make sure you are prepared to begin work before opening gas supply. 5. Do not use oil, grease or thread seal tape on any connector. 2. To prevent explosion, use reverse-flow check valves and flashback arrestors (sold separately) on the base of the Torch. 6. Use clamps (not included) or other practical ways to secure and support the workpiece to a stable platform.
b. Touching the Tip against the workpiece. c. Overheating the Tip. d. An obstruction in the Tip. If backfire occurs, close the Torch Handle Valves (oxygen first, then acetylene) and after remedying the cause, relight the torch. 9. FLASHBACK: Flashback is a condition that results when the flame flashes back into the Torch and burns inside with a shrill hissing or squealing noise.

Assembly Step 2: Crack Each Cylinder Valve WARNING! KEEP WRENCH ON ACETYLENE CYLINDER’S VALVE whenever cylinder is in use to allow quick shutoff in case of emergency. NOTE: Wrench not included. 3. Attach the Green labeled Oxygen Regulator (9) to the Oxygen Cylinder (13) and the green oxygen hose to the regulator. 4. Attach the Red labeled Acetylene Regulator (10) to the Acetylene Cylinder (14) and the red acetylene hose to the regulator, tighten counterclockwise - threads are reversed.
Tool Set Up 2 of 3 - First Leak Test: Soapy Water This test detects major leaks. Safety 1. After everything is connected, close both Torch Handle Valves, turning clockwise. Close regulators, turning knobs counterclockwise until loose. WARNING! KEEP WRENCH ON ACETYLENE CYLINDER’S VALVE whenever cylinder is in use to allow quick shutoff in case of emergency. 3. Adjust the oxygen regulator to deliver 20 PSIG. Adjust the acetylene regulator to deliver 10 PSIG. DO NOT EXCEED 15 PSI ACETYLENE PRESSURE.
Gauge Leak Analysis Oxygen shown. (Procedure also applies to acetylene.) leak inside regulator leak after regulator Have the regulator repaired by a qualified technician. Oxygen shown. If Cylinder gauge moves as shown, and Delivery gauge stays still THEN leak before regulator If Delivery Pressure decreases The leak is at the regulator outlet connection, within the hose, at the torch inlet connection or at the Torch Valve on the Torch Handle.
Welding Safety Welding Tip Pressure Settings This Torch Handle is capable of welding metals from 1/32″ up to 1-1/4″ thick. The included Welding Nozzle, size 0, will weld metals up to 1/16″ thick. Check the thickness of the metals to be welded and use the chart below to choose the size nozzle for the job. If welding metals other than 1/32″ to 1/16″ thick, a different welding nozzle will be needed.
Welding Instructions Inspect tool before use, looking for leaking, damaged, loose, and missing parts. If any problems are found, do not use tool until repaired. 2. Close both valves on the Torch Handle securely. 3. Adjust the Acetylene and Oxygen Regulators to their proper working pressures, see Table A on page 10. DO NOT EXCEED 15 PSI ACETYLENE PRESSURE. Acetylene Delivery Pressure DO NOT EXCEED 15 PSI.
5. Open the Acetylene Torch Valve about 1/4 turn, and quickly ignite the acetylene gas coming out of the Nozzle by squeezing the handle of the striker, creating a spark. SAFETy WARNINg! Do not use matches or a butane lighter to light the Torch. Striker (3) Acetylene (gAS) Torch Valve 7. Flame Adjustment: a. Starting to Add Oxygen: Slowly open the Oxygen Torch Valve.
Welding Shutdown Instructions Note: If the tank gauge still has pressure, the Oxygen Regulator needs to be opened. 1 Bleed pressure on both gauges to 0 Oxygen (OXY) Torch Valve 2 Shutdown Step 1: Close Torch Valves 2. Fully close both cylinder valves, turning clockwise. Shutdown Step 4: Open Oxygen Valve Safety 4. Open the Oxygen Torch Valve counterclockwise to allow all the pressure to bleed out. Setup 1.
Cutting Safety Cutting Tip Pressure Settings The Cutting Attachment is used to cut metal up to 3″ thick. The included tip, size 0, cuts metal up to 1/2″ thick. Check the thickness of the metal to be cut and use the chart below to choose the appropriate size tip for the job. If cutting metals over 1/2″ thick, a different tip will be needed.
Cutting Instructions Inspect tool before use, looking for leaking, damaged, loose, and missing parts. If any problems are found, do not use tool until repaired. 2. Close all valves on the Torch Handle and Cutting Attachment securely. 3. Adjust the Acetylene and Oxygen Regulators to their proper working pressures, see Table B on page 14. DO NOT EXCEED 15 PSI ACETYLENE PRESSURE. Acetylene Delivery Pressure DO NOT EXCEED 15 PSI.
5. Open the Acetylene Torch Valve about 1/4 turn, and quickly ignite the acetylene gas coming out of the Nozzle by squeezing the handle of the striker, creating a spark. SAFETy WARNINg! Do not use matches or a butane lighter to light the Torch. 8. Flame Adjustment: a. Starting to Add Oxygen: Slowly open the Pre-heat Oxygen Valve.
1. After work is complete, first close the Oxygen Torch Valve clockwise, then close the Acetylene Torch Valve clockwise. Oxygen (OXY) Torch Valve 1 4. Open the Oxygen Torch Valve counterclockwise and open the Pre‑heat Oxygen Valve counterclockwise to allow all the pressure to bleed out. Note: If the tank gauge still has pressure, the Oxygen Regulator needs to be opened.
Maintenance Instructions Safety Procedures not specifically explained in this manual must be performed only by a qualified technician. TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Close the oxygen, then acetylene and allow the torch to cool completely, then disconnect the hoses before performing any inspection, maintenance, or cleaning procedures. TO PREVENT SERIOUS INJURY FROM TOOL FAILURE: Do not use damaged equipment.
