For example, if the wire size is 0.23 inches (used for sheet metal), then you need to multiply by 3.5 inches per amp, which is equal to 437.5 ipm. .023 inch Multiply by 3.5 inches per amp. .030 inch Multiply by 2 inches per amp. .035 inch Multiply by 1.6 inches per amp. .045 inch Multiply by 1 inch per amp.

That said, while thickness is always significant, the actual amperage difference can vary a great deal depending on the type of metal being welded. In the case of aluminum, for example, a good rule of thumb in TIG welding is 1 amp per 0.001 of thickness. That said, this rule begins to break down at more than ¼ inch in thickness.

Beta Radiation in Thickness Control. In industries involving the production of materials with a specific thickness i.e. paper, plastic films, aluminium foil, steel etc beta radiations are used to measure and control the thickness. Strontium 90 is an example of a radioisotope used for this type of application.

Pasta machines are elegantly simple so maintenance or repair is relatively straight forward. In many cases cleaning, lubrication, retightening or replacing parts will fix most problems. The gears and other areas where metal meets metal might need lubrication. I use silicon grease or vaseline.

The optimum value of these parameters varies with the type of metal and its thickness.

The newer S Series ice machine also uses a single wire probe, however the newer ice thickness control has a longer plastic base and is not interchangeable. The part number for an S Series ice thickness control is 200802. Ice thickness or bridge thickness can be set by turning a screw located on the ice thickness control.

The type of metal to be cut, thickness and the cut face weld-ability required will determine which gas combinations are recommended. In an effort to deliver premium cutting performance, manufacturers of automated plasma systems make large investments developing consumable sets designed to operate at exact amperages using specific gas combinations.

The desired bridge thickness is 1/8″. To crudely gauge that, I've used (or once used) a 3/16″ Allen wrench as a thickness measurement tool to preset ice bridge thickness. Stick that little wrench in there in between the sensor and the evaporator plate, then adjust accordingly to 3/16″.

With the material thickness known, use a feeler gauge on both the tool's inboard and outboard sides to preset the roll tooling gap, adjusting the vertical distance between the upper and lower shafts (see Figure 6). The pre-gap procedure—determining the gap before the material is in the rolls—checks for clearance.

As a starting point use the thickness as the radius. For example I have two different 10 gage carbon steel gages in my gage table. One for short bends one for long bends. A 6 " part is bent much tighter than an 8' part being bent on the same machine. The bend radius controls many things. Most importantly the size of the flat pattern around the ...

Use test strips of metal, approximately 3 inches by 3 inches each, of the thickness you will be forming for the following adjustments. Step 1. Check clamping pressure by clamping test strips in the brake approximately 3 or 4 inches away from each end of the brake. Set the clamping pressure so that it is enough to keep the material from slipping ...

Some machine models are also provided with exit side pinch rolls to further improve the gripping and pulling capability of the machine. The amount of pinch roll force required for a specific material is based on the material width, thickness, and surface condition. High thickness materials normally require greater pinch roll forces.

A machine guard needs to be generally robust. To guard against people accidentally putting a hand into a machine, I'd use 1.5mm steel. If the metal is much thinner than this it may be difficult to weld or may distort in use. If the metal is much thicker than this it may be too heavy and unnecessarily expensive.
