Frequently Asked Questions
What types of gas are compatible with these hand torches?
Both the LV-2B and LV-A torches are designed to be used with MAPP, Propane, and LPG gases. They connect standardly to CGA600 cylinders (14.1-16oz / 453.6g containers).
What is the maximum flame temperature they can reach?
The torches can generate a high flame temperature of over 3600°F (tested with MAPP gas), which allows for shorter welding times and lower gas consumption.
Are the torch bodies made of durable materials?
Yes, the main components of these hand torches are manufactured from high-quality Brass. No Aluminum is used in their construction, ensuring superior durability and safety.
What is the difference in tubing size capability between the LV-2B and LV-A models?
The LV-2B DualTip torch can handle soft solder up to Max. Φ6” and brazing up to Max. Φ3”. The LV-A Self-Ignition torch handles soft solder up to Max. Φ4” and brazing up to Max. Φ1-1/4”.
Can the torch tips rotate for different working positions?
Yes, both models feature tips that can spin 360 degrees, providing maximum flexibility and ease of use in various angles and tight workspaces.
Why should I avoid setting the flame too low?
Operating the torches at a low flame setting will restrict the proper gas flow required to cool the system, resulting in the overheating of the torch tip. It is recommended to adjust the flame to a proper working level.
