question for all electroheads...
i have an oxford migmaker which has a copper wound (ooh!) transformer and similar switchgear to the portamig and mta machines.
i know that mig welders exist in the mta format as a welder/booster/charger set up and i want to convert my oxford to that. the large step voltage/current switch has 2 spare positions whcih are doubled up with the existing 1 and 2 positions but they could easily be rewired to be charge and boost. the transformer could be used to provide a suitable voltage by connecting the correct tapping and all that leaves is a circuit which would control the charging which i think i could get from a normal charger. wouldn't think electronic circuitry is required for the boost function.
has anyone got one of these machines or does anyone have a bit of experience to help me do this?
