About Us WPI Taiwan

About WPI Taiwan
Founded in 1975
W.P.I. Taiwan is a professional manufacturer of suspended spot welders. With over 40 years of experience, W.P.I. Taiwan is well versed in the design and manufacture of "compact" welders which create maximum power in limited space with our energy-saving transformers and cylinders. W.P.I. Taiwan's Suspension typed and portable welders are the smallest of their kind in terms of power, making it the first and most important and professional Taiwanese manufacturer in the country.

For diversified development, W.P.I. Taiwan has developed a wide range of automated machines, including multi-spot, multi-axis , servo-mobility on XYZ axes, and multi-station machines, which are customized according to customer needs. In addition, W.P.I. Taiwan has designed "Auto-Alignment Welding Machine ", which is auto correcting the electrode coordinate to adapt electrode wear, thus eliminating manual adjustment and the unexpected interference with the workpiece.

W.P.I. Taiwan is trusted and recognized by automotive sheet metal assembly plants in Taiwan for its resistance welding engineering design and spot-welding technology research. As to W.P.I. Taiwan’s customized machines, they are mainly for the steel furniture industry, such as steel cabinets, tool carts, air conditioning cabinets, etc. Please refer to our "Video Gallery" for various machines’ operating videos, including Suspension Spot Welders, Automatic Customized Machines, Pneumatic Rocker Arm Welder, and Tip Dresser.

Energy Saving in WPI Gun
Transformer, Secondary Cable, Performance Output
Fully concealed one-structure in compact size and no secondary cable need. No current loss and achieve 90% of working efficiency rating.
48KVA of WPI Guns efficiency current output equivalent to 165KVA Cable Gun.
Energy Efficiency
Small KVA in high output and no current loss. High efficiency and energy saving choice.
Small, nimble and 360° rotational use. Great maneuverability.
Transformer, Secondary Cable, Performance Output
Bulkiness transformer with clumsy secondary cable cause current loss and reduce 40% of the working rating.
Energy Efficiency
High KVA requires high power supply. Larger power is needed to compensate the loss of the seconday cable. Electrical energy costs will increase.
The bulkiness of the secondary cable limits the meneuverability and causes poor operability.
