And how may i ask did you make this?Originally posted by Pin Head:
<STRONG>I don't know specifically about Mobi weld, but I have a Jeff Fretwell "option #2" home brew welder and I can compare it to the claims made by some of the other companies.
Some of their claims are hype; some are not:
High frequency DC! They are all high frequency DC, even stock alternators and it doesn't really matter.
Hand wound stator, 12 gauge! My stock Ford 90A alternator has 12 gauge wire in its stator, but it is probably not hand wound.
110 V DC outlet. The stock Ford alternator will easily put out 110 V DC to run brush type power tools. The big difference is on the commercial products the 110 V is regulated; I have to regulate mine by regulating the engine speed.
Runs 1/8 inch rod. My 90A alternator will light and burn 1/8 rod at an engine speed of about 2,500. It easily runs 3/32 rod at 1500 RPM.
Only draws 4-7 A from your battery while welding! The stock Ford 90A alternator only draws 7A at full field.
This is not hype: Cost difference -
Commercial welder $500-1000
Home brew $50 including cables. (I'm not using the 110V regulator)
