When working with copper pipes are compression fittings good enough to use or is soldering recommended?
Dodge9wolf
compresion fittings usually work well if u have any problems use some sealing tape If you are going to have the pipes in wall use solder, any copper exposed you can use compression.

Naturally it takes the body to excrete THC 3 months from the body. THC is stored in the fat cells so it depends on body composition. To speed the process working out and drinking more water is recommended.
Touch lamp not working after blown bulb you changed bulb but lamp still will not go on by touch only by the plug can this be fixed?
Im currently trying to repair mine. Apparently a thyristor is the problem. I have a wall-o-brokenCircuitBoards and am trying to use thyristors from an lcd power supply but they seem to be dead, or the heat from the soldering gun is killing them before they even get a chance. I hope you fix yours. Heck, I hope I fix mine.

Good wetting, high strength, low creep, high corrosion resistance, high thermal conductivity, high surface tension, zero wetting angle. Suitable for step soldering. The original flux-less alloy, does not need flux. Used for die attachment and attachment of metal lids to semiconductor packages, e.g. kovar lids to ceramic chip carriers. Coefficient of expansion matching many common materials. Due to zero wetting angle requires pressure to form a void-free joint. Alloy of choice for joining gold-plated and gold-alloy plated surfaces. As some gold dissolves from the surfaces during soldering and moves the composition to non-eutectic state (1% increase of Au content can increase melting point by 30 °C), subsequent desoldering requires higher temperature.[76] Forms a mixture of two brittle intermetallic phases, AuSn and Au5Sn.[77] Brittle. Proper wetting achieved usually by using nickel surfaces with gold layer on top on both sides of the joint. Comprehensively tested through military standard environmental conditioning. Good long-term electrical performance, history of reliability.[29] Low vapor pressure, suitable for vacuum work. Generally used in applications that require a melting temperature over 150°C.[78] Good ductility. Also classified as a braze.Au98Si298Si2370/800[12]-Au98, Indalloy 194.

[76] AuSi3.2 is a eutectic with melting point of 363 °C. AuSi forms a meniscus at the edge of the chip, unlike AuSn, as AuSi reacts with the chip surface. Forms a composite material structure of submicron silicon plates in soft gold matrix. Tough, slow crack propagation.[44]Au87.5Ge12.587.5Ge12.5361 356[12]-yesAu88, Indalloy 183.

High-temperature, extremely hard, very stiff.In10099.99157-pureIn99. Used for die attachment of some chips. More suitable for soldering gold, dissolution rate of gold is 17 times slower than in tin-based solders and up to 20% of gold can be tolerated without significant embrittlement. Good performance at cryogenic temperatures.[80] Wets many surfaces incl. quartz, glass, and many ceramics. Deforms indefinitely under load. Does not become brittle even at low temperatures. Used as a solder in low-temperature physics, will bond to aluminium. Can be used for soldering to thin metal films or glass with an ultrasonic soldering iron.[31]

Why do you think a low-power soldering iron is suitable for electric work?
When working on computer boards or any electronic equipment, heat can ruin the item. A low wattage soldering iron it only creates enough heat to melt the soder. Do not use acid core solder on any electrical type soldering jobs.
Where are the grease fittings located on a 1998 GM Jimmy?
they are everywhere...any where there is a joint or working, encased, parts.
Why is a low-power soldering iron suitable for electronic work?
When working on PC boards or any electronic equipment, heat is the biggest enemy. A low wattage soldering iron is the best because it will generate only enough heat to melt the solder and not heat up other adjacent components that are near to the point that you are soldering. Also when working on electronic equipment use a solder with a low melting point. There is a special low temperature solder with a rosin core that is made especially for PC boards. Never use acid core solder on any electrical soldering jobs.

All Sizes Don't Fit All With Plumbing Fittings?
Plumbing fittings come in all sizes, and to make sure you have the right fitting for the job, you need to measure the pipe you are working on. Just because you are working on plumbing for your entire home does not mean that all the pipes will be the same size. Different rooms in the home require different types of pressure, so the pipes and the fittings will be different sizes. Fittings in the kitchen and bathroom sinks will most likely be smaller than those in the shower or washing machine.
Disinfectant recommended when working with body fluids?
Bleach
