How to do spot welding circulating water tank?
Spot welding water cycle General requirements: more than 10l/min of water flow, because the spot welding will heat up, so if the self cooling water tank, water tank volume can not be less than 100L, if the air cooling water tank volume of 10L above.The above data is based on the standard of 100KVA welding machine. Other parameters that can go up or down.
Your spot welder is not very big. Go to the goldfish store and buy a small water pump. Use a bucket with half a bucket of water, and then connect the pipe. The return water flows back into the bucket
In order to guarantee the service life of welding electrode and the stability of welding quality, the resistance spot welder can not make the circulating water tank of itself.Resistance spot welding voltage using low (only a few volts), the welding time is short (millisecond), greater welding current (3000 amperes minimum to tens of thousands of Amperes), the motor pressure makes the electrode crushing local formation of a resistance welding welding process.Resistance spot welder must use special circulating water tank and water pump to ensure proper water delivery pressure and water flow. In order to better cool the electrode, not to the electrode because of poor cooling, excessive non long-term wear and tear. Or adhesion between the electrode and the workpiece.
