Welding Using Torch. Listen for running gas to ensure safety. For pipe welding however a particularly compact torch is required ideally one that is small and flexible with a short torch cap.
This torch is used for many purposes and in many industries. The automatic and manual torches are similar in construction but the manual torch has a handle while the automatic torch normally comes with a mounting rack. Allow the propane torch to cool down and then store it in a dry location.
The outer jets are for preheat flames of oxygen and acetylene.
The knob is located on the shorter of the 2 tanks on the torch. Unfortunately butane torches are not on the list of a welders tools. Manual pulsing on aluminum tubing use 2t setting along with 0 upslope and 25-3 seconds of downslope. Put Your Butane Torch to Good Use.
