Hi can anyone give me some information about a saf hfc 250 tig was told it was a stand alone machine but can’t find any details online I’ve plugged it in and won’t arc .so I’m thinking it’s got to be powered by another machine any help much appreciated
Cheers that’s what I thought I’ve got a migatronic lehf dc tig with stick welding capability can I hook up to that and if so what amps should the migatronic be set at to be safe cheers
Was for sale on a lot of sites I notice, the wording is a bit suspect regarding "in working order" no mention of requiring extra unit to make this happen
Cant find any reference http://www.alw-tool.com/IMPC/Saf-Fro/EN#results
Old stock or ?? country
As said, it's a add on unit to give HF to a unit with no HF
Judging by the name of your migatronic it probably already has hf anyway.
The dial is for setting the time for post flow for gas.
If your migatronic has hf and gas control then you won't gain anything by adding this on.
Fyi. You would set the power you need to use on the source welder then this unit will just pass that amount through and add hf over the top of it. Max input would be 250 amps or 200amps continuos use.
Only time I have ever found one of them usefull is for stick welding with rusty metal. Also helps damp rods strike up better but be prepared to get a reasonable amount of electric shocks if using with stick.
