Finally considering an arc welder. I still must decide between buying/building either a transformer type or one based in a truck alternator. Pricewise, buy/build the transformer (copper wire, iron laminate, etc) seems similar to build the alternator type (motor, alternator, battery, etc). There is another consideration: The effect of the load on the house appliances . When repair guys have been at the house the lights have flickered noticeably, even wiring their transformer directly to the breaker panel. I have voltage regulators at the computers, the tv and cable box but the flicker seems a bad thing to do to the house in a regular basis. If I did my math right the load for a 2HP motor would be about 8 amps, less than input amperage required for an useful transformer. Please correct if wrong. So do you guys with tranformer welders do something to alleviate the problem of simply live with it?
BTW, right now my OA rig is near empty, but since I cannot spare $$ from food and bills until year's end or so I will build a water resistor. Long ago I got from Lindsay's the booklet that explains how to do it and the materials are around the house, so the cost would be zero. Note that I have a3-phase 208V 50amps outlet (yes I checked that), so any suggestion for improvement is welcome.
