It is tempera- ture variable within the range of 500°C to 1300°C depen- dant upon the function used. Refilling takes only a few seconds and it operates approx. 1 hour with one filling. An integral sight glass shows the level of the gas in the tank. Ignition of the gas requires an external source and the long life tips deliver rapid heat up. The hot blow nozzle supplies inert hot gas to prevent oxi- dation of non contact solder joints and is therefore suita- ble for use in solder paste applications, heat shrink and on vinyl chloride boards.

  • Make a Portable Workstation
    instructables Make a Portable Workstation by Benne I recently started working on my own tutorial blog, makerguides.com. I currently have written several Arduino tutorials on using sensors and controlling stepper motors: How to control a stepper motor with A4988 driver and Arduino HC-SR04 ultrasonic distance sensor tutorial 28BYJ-48 Stepper Motor with ULN2003 Driver and Arduino Tutorial Feel free to check them out and maybe leave a comment with some feedback, thanks! Need parts for your project? Check out my Amazon Affiliate link below: http://amzn.to/2mVlbnl After having finished my CNC router (see my other Instructable), my workshop (a small shed in my backyard 3 x 6 m), became pretty full. The only other tools that I can fit in there are a small table saw, a drill press and some small powertools and handtools. So most of my woodworking happens outside. Next to woodworking and CNC stuff, I also like to work on smaller projects with electronics, which requires soldering etc. Since my 'workshop' is pretty full, I didn't have a proper place to work on these smaller projects. So I just moved some of my smaller tools (screwdrivers, soldering iron, pliers etc.) into my bedroom and worked on my electonics projects there. My parents were ok with the fact that I did some soldering in my bedroom, (better than in the kitchen or the living room), but didn't like the fact that my tools were laying all over the place. The table I was doing my work on also became pretty dented and full of glue and solder blobs.

When fully soldered, copper roofing can provide a watertight, durable roof with a decades-long service life; how­ ever, these roofs are highly dependent on proper design and careful craftsmanship during installation. The presenters will discuss common issues with fully soldered metal roofing, including improper accommodation for thermal expansion, improper rivet or joint detailing, and drain details for contemporary copper roofs that incorporate membrane underlayment. Speaker Nicholas Floyd, PE — Simpson Gumpertz & Heger Inc. NiCK FlOYD is a senior project manager who specializes in the investigation and remediation design of building enclosures. His past and current copper roofing design and investigation projects include historical and large public structures, including the New York, massachusetts, Kansas, and iowa state capitol buildings. Floyd also has experience design­ ing and investigating various membrane roofing systems, slate roofing, masonry, plaza and below-grade waterproofing, fenestration systems, and architectural terra cotta.

  • Safe Soldering Work Practices
    Safe Soldering Work Practices Soldering is the process of combining two base metals via a filler solder metal with a lower melting point. In this process, the metals being joined are heated to the soldering temperature but do not become liquid, only the solder liquefies. In addition to the joint and the base metals, soldering operations may involve the use of fluxes, coatings, and cleaning agents. Soldering presents potential exposures to the materials and by-products via inhalation, skin contact, and hand to mouth routes. The use of lead-containing solder presents the potential for exposure to lead, which can cause neurological toxicity and other health effects. The use of rosin core solder or flux presents the potential for exposure to rosin fume, which can cause irritation and sensitization of the eyes and respiratory tract. The high temperatures of the solder gun and melted solder create the potential for burns or an ignition source for combustible materials. This safe work practice applies to electronic hand soldering using a soldering iron or soldering gun. Safe work practices for torch soldering are contained in the HVCC Hot Work Safety Program. This document and safe work practices should be used by all employees and department heads performing electronic soldering to ensure awareness of the hazards and minimize any hazards posed by soldering operations. Safety Precautions 1) Soldering Iron Safety • Never touch the element or tip of the soldering iron. It is very hot (about 400°C) and will burn. • Hold wires to be heated with tweezers, pliers or clamps to avoid receiving burns from objects that are heated.
