2 EL/2006/5011C 1982 was founded in 1982 with a 200 sq.m. factory on Chung-lou Road in Shalu Township, Taichung County in Taiwan. The product line included oil-cooled transformers for electrical and mechanical systems, with sales to plumbing and electrical contractors, factories and public construction contractors OA The company later developed transformers for pneumatic spot welders, seam and butt welders as well as versatile, highly portable transformers for capacitor-type welders. These were marketed to machinery manufacturers and widely used in automobile and motorbike assembly, parts production, OA equipment manufacturing and the production of display cases Transformers for use in high frequency induction melting furnace, with sales to electrical appliance manufacturers The company now boasts a 3000 sq.m. in the Taichung Industrial District and is backed by capitalization of NT$50 million HFHB CNC Later developments included H-class, F-class, H-class filed-type, B-class injection molded-type and dry transformers for circuits, with sales to makers of CNC machine tools, electrical and plumbing contractors and public construction contractors Resistors for inverters, start-up resistors for motors and resistors for capacitors IC High-tech products are also available such as single and three-phase Inverter DC type welding transformer that are suited resistance spot welder, Butt, seam various resistance type welding machine and Vacuum metailizing machine. Patents for these products were applied for in 1999 and obtained for Taiwan and China in Volume production then began, with sales to electrical machinery producers, defense department manufactures, IC component assemblers, automobile and motorcycle plants and other parts manufacturers KVA PCOA A new 6KVA portable spot welder was introduced featuring adjustable current and welding time and a newly-developed high-tech PC control panel. This machine is designed for use with machine bodies, automobile bodies and in office furniture factories Develop products include high-tech precision DC power supply for wastewater treatment in wafer fabs and in compound circuit board electroplating operations KVA Research and develop KVA inverter welding transformers for use in inverter type spot, flash and application covers a variety of materials, such as aluminium, bronze, stainless steel, iron plate, etc (INVERTOR) Also develop time-controlled inverter-type resistance welder.

4 OXYGEN-FREE COPPER WELDER FEATURES Medium temperature soldering copper tube produces no oxidized materials and degenerated. The welded joints will be not oxidized that leads to the refrigerant leakage and block the cooper tube YSVRV20 YSVRV20U INVERTER ARC STICK WELDER GREEN WELDERS YSIW-200 Inverter ARC Stick Welder 10KVA 160A Features 1. Saving the electricity for more than 50%; the lightest in the world; adopting the state-ofthe-art IGBT semi-conductor; the breakdown rate is fifteen times lower using Mosfet semi-conductor that is sold in the market. 2. The use amount of the frequency converting electric welding machine's power line can be a half lower than average electric welding machine's power line, for example, if you must use 22 square millimeters for average electric welding machine's power line, you only need to use 8 square millimeters for the frequency converting electric welding machine's power line; it can decrease the weight for you to carry, as well as the cost of purchasing the electric wire, because the frequency converting electric welding machine can save more than 50% electricity than average electric welding machine. 3. The frequency converting electric welding machine's weight is more than three times lighter than average electric welding machine; hence, if you carry it out to use, it can decrease the personnel's physical burden, and heighten the personnel's work efficiency. 4. The welding of the frequency converting electric welding machine is direct current, and it's different from average electric welding machine's alternating current that is easy to produce electric shock, and cause the staff's accident, injury, or death. 5. The DIP switch attached to the frequency converting electric welding machine has the standard and electric shock proof functions; if it's switched at the electric shock proof function, it's easier to do welding at electric shock proof function, and it can promote the work efficiency.

Leave it cool down for a while then soldering is done. 5 Soldering the remaining unused copper tube by joining them so that material cost-saving is increased, and allows more effective use and avoid wastes.
