F A Q (General)


Yokodai.JP Personal Spot Welder  WELDING CAPABILITY
How thick are the metals
Yokodai.JP Desk Spot Welder can weld?

Desk spot welder, in consideration for safety, uses low voltage and small current?thus it can only be used to weld thin metals. Depending on the model, it is able to weld stainless steel wire up to 1.5 mm in diameter, or nickel plate up to 0.15mm in thickness. (However, the current flowing in the metals reaches from hundreds to thousands ampere)

Can Yokodai.JP Desk Spot Welder
weld any kind of thin metals?

Using desk spot welder, depending on the way of using the electrodes, stainless steel or nickel up to 1mm is possible to weld. Gold and silver, copper, aluminum and other metals which are easily electrified, the welding thickness is limited under 0.3mm. For aluminum foil, the limit is around 100mm.
The table below shows the materials which are possible to weld and assumpted various use of Yokodai.JP spot welder. However, since the material's surface condition and structure affect the welding process, we cannot guarantee the welding possibility of a material.
