Propane Torch (by Robert,OntarioCanada [ON]) Posted on: Jan 21, 2023 9:15 PM

Bought a 20 lb. propane tank and propane torch with connections where the connection to the torch without using a regulator. Natural gas and propane devices use a regulator to reduce pressure going to stove, heater or any other device. A propane torch is used to clean up yard where a lot heat is required. No one seems to know a lot of those torches where they sell them at farm stores and some other tool places. The torch is about a meter or 3' long.

Robert, not sure I read a question there, but will share with you my experience.

I have sold this type of torch and repaired propane/LP tanks where I work for years.

I have used them many years without incident.

These type of torches don't need a regulator to operate. The intensity of the flame is regulated by either a valve on the torch or directly using the valve on your tank.

The main problem I have found is several years ago when the government mandated all valves on tanks of capacity of less than 100#'s of liquid be replaced with safety valves, OPD valves that have a triangular shaped handle.

The new valve has an automatic flow restrictor built in to limit the maximum amount of gas that can be released.

This new valve is called an OPD valve, "Overfill Protection Device" because it also has a float device attached that hangs down inside the tank that prevents overfilling by closing the tank refilling process from the inside.

Somewhat how a toilet fill valve does when the tank has filled to the proper level after a flush.

This new OPD valve will automatically stop or reduce the flow of gas if it senses that too much gas is flowing out of the tank, like for instance if a line is cut and and gas is released uncontrolled.

The torch you are using does require a high flow of gas to operate properly. So when lighting this torch using a tank that has a OPD valve, turn on the valve very slowly to prevent a sudden rush of gas that will activate the flow restrictor inside the safety valve.

You can avoid this gas limiting problem by using a larger 100# capacity tank or an old style 20# tank most commonly found on BBQ grills.

Since it is normally illegal to refill tanks with the old valve, you can bypass that requirement by writing "TORCH TANK" on the tank itself that lets a place like ours that refills tanks know the user is aware of the differences between the operation of old high flow valves and the new OPD valves.

Side note, places that exchange the 20# propane cylinders in our area do not fill tanks to rated capacity of 20# like we do. If you read the label it will say tank only has 14#-18# of gas in it.

We currently charge $20 to refill a tank to 20# and the exchange places here charge $20-$22 so you are paying about 30% more, but the normal person sees the same size tank and doesn't realize they are getting much less gas for their money.

Hope this helps.

IF this is a roofing torch to apply modified rolled goods, then you should have an adjustable regulator so you can set the flame of the torch. Sometimes Harbor Freight used to sell LP torches without a regulator, BIG MISTAKE!

Lowe's sells them. Use caution. Think responsibly. Read the directions.

The torch and connection hose came with no instructions where realzied that torch and hose were sold in Us at Harbor Frieght where Harbour Frieight does not exist in Canada. Wanted to be sure as propane tanks this size are considered very dangerous where must not bring indoors. I bought tank at Costco where here they refill 20 lb propane tanks. The person ahead put the propane tank inside back of pickup truck whwre would never do that as put propane in bed of pickup truck while securing with cables. Some places exchange where prefer to bring own propane tank for refill. The output of the torch is 500,000 Btu which output is larger then the size of the gas boilers used to haat a 15 unit apartment buildiing. The main raason for buying torch is to clean up backyard house as across the road they called building inspector where they wanted the yard where no material at alll as cleared up all the yard where removed everything where the yard was wild. They complained about noise where used a wood chipper to break everything down. When it snows going to continue to clear up section by section as is illegal to make a bonfire in backyard. Now only a few inches of material. Found the building inspectors in town the worse I had to deal with where in different towns had some tenants complain about things where cleared everything up. One complain about mold in bathroom where she was doiing laundry in bathtub where did use commercial washing machines and clothes dryers in apartrment where to the head inspector then showed pictures of laundry room as the other inspector did not listen to me. She also ruined the grout in the living room where re grouted then over with She was angry with me as called the police that her boyfriend was beating her up then boyfriend was arrested that night where never was allowed to come back to apartment building. She finally moved out then over with. Safety with any industrial equipent is important where always read manuals as have welding equipment, chainsaws and other saws. It is better to personal protection equipment like gloves, safety goggles or a mask if a lot of dust.

Robert, in the past Carolyn [MO] has posted pictures of her & her weed eating flame thrower. You might find them in the picture section.

Thanks for the post. You maybe are about to get another customer. When I get to your side of the state I will stop in and talk to you. (When I remember. It's an age thing)

I have a little run-down tax sale place over in Circle City (nine miles other side of Dexter). Been wanting to clean it up but too much work. I did buy me a little bulldozer a bit back. It is mfg. by ATECO. Itís not a D9 Ė more like a D 0.5 (small). Went over and played with it and got a lot of brush cleaned up in just a couple of hours.

Now I need to decide if to doze the house down or fix it up.

Anyway. Thanks for the info on the tanks.

Three harbor freights in the Buffalo area and one in Erie

There is a store in Canada called Princess Auto which has a wide selection of all types of tools along with other products where the Propane Torch did not have a manual where have one tool from Harbour Freight where someone brought in from the Us. I try to buy power tools or other equipment that is UL or CSA approved as non certified power tools can not legally sold here where in Quebec no certification is required. The closest Harbour Freight is in Niagara Falls New York which is 180 kilometres away where with high price of gasoline it is not worthwhile for the drive. I am in process of getting a new passport which should arrive soon. Next time will go into Harbour Freight website then download a manual. Prefer Makita power tools as a little more expensive than other brands where they last a long time. On Amazon and Ebay it is possible to buy electrical items with no certification at all.

Iíve used a weed torch on brick pavers and found it tedious work w uneven results as most weeds have tap roots. Hi test vinegar and salt have been better in my opinion but you need to wear ppe.

Greg thanks for the explanation.

Propane Torch (by mike [CA]) Posted on: Jan 25, 2023 2:37 PM

the weed torches you pick up at Tractor Supply or Harbor are probably unregulated. the ones we use on the roof are regulated and cost more than the ones you'd use for the weeds or snow. both have a valve on the torch before the trigger to tweak the flow. for weeds the cheapos are just fine.

they're also handy to light cigarettes, keep the neighbors cats off the patio, roast weenies, and make short work of getting the campfire or briquets lit! lots of uses around the house --75.80.xx.xx
