It has been quite a while since i have posted. Well i finally tested the spot welder controller about a week ago. It worked perfect the first time, no tinkering required. I have a great deal of control over the weld. For example i can weld two peices of 24awg stainless wire -Length-Wise-. Or i can burn a hole through two peices of 22gauge stainless sheet.
I am considering changing the power factor method. At the moment i simply wait for the zero crossing of the mains and then enable the current transformer and begin to count consecutive waves. This works, but it seems to be very peaky. If i evenly distribute the ratio to 1 second it should distribute the heat more evenly. At the same time this will give me the ability to specify another control parameter. I will be able to adjust the term of the of ratio so that i can fine tune the weld.
I have no pictures at the moment.

Spot welding is typically used when welding particular types of sheet metal. Thicker stock is more difficult to spot weld because the heat flows into the surrounding metal more easily. Spot welding can be easily identified on many sheet metal goods, such as metal buckets. Aluminum alloys can be spot welded, but their much higher thermal conductivity and electrical conductivity requires higher welding currents.
I’m Артур Борис a resident/citizen of the Republic Of Russian. I’m 52 years of age, an entrepreneur/businessman. I once had difficulties in financing my project/business, if not for a good friend of mine who introduced me to Mr Benjamin Lee to get a loan worth $250,000 USD from his company. When I contacted them it took just five working days to get my loan process done and transferred to my account. Even with a bad credit history, they still offer their service to you. They also offer all kinds of loan such as business loans, home loans, personal loans, car loans. I don’t know how to thank them for what they have done for me but God will reward them according to his riches in glory.
