kCap, kSupply, Lead Acid battery, LIPO battery, power sources for kWeld -

kWeld is a very capable battery spot welder. It can handle up to 2000 amperes of current at up to 30 volts. You are best to aim for 1500 to 1800 amps at 12volts or less to achieve a good level of performance. A very common question we get is how to select a good power source.  Continue reading to learn about three common power source options.


inductance, Q&A for kWeld, wire gauge, wire gauge to diameter, wire length -

Calculating the inductance of the kWeld circuit Your kWeld spot welder came with a set of stock wires which many are tempted to change. We encourage the DIY mentality and love the fact that you rewire masters share your mods and experiences with the community on kWeld World. This article is written to help you understand the impact changing wire length and diameter (gauge) can have on inductance. Firstly, please understand that too much inductance can damage the kWeld unit. Increasing the wire length and related inductance also reduces the maximum current your kWeld can handle safely. Hence, in the...
