Need Thoughts on Miller legend 200le aead and lincoln HI-FREQ box

[gaswelder]

I am new to this forum, this is my first post. I have a Miller Legend 200le aead gasoline welder, a 1988 model, and a Lincoln Hi-Freq box. I would like to try to use the Hi-freq box and try tig welding. If I hook the box up to the welder will it harm my Miller gasoline welder. I have read on line something about a kit being installed to prevent hi-freq backup, but I have no kit, and don't know if I need one. Any thoughts on if it will hurt the welder ? Thanks

The electronic parts of that miller will be fine if you connect it correctly. I use 2 hf boxes on a regular basis. The miller hf251 and an arc pig. I never use the high frequency cap filters. Use good ground connections on everything around it and you should be fine. I have an extra set of the hf filters for free if you want them. I don't bother using them and have never had an issue. I don't have a lincoln brand hf but my miller and arc pig do the same thing basically..I've run my pig on 3 or 4 different machines gas and electric drive. Used my miller hf251 on my indoor electric machines only.

You can run that aead on dc and scratch tig steel without hf.

Thanks for the information, I would like to use ac and do some aluminum.

I also would like to have your filters, if you are not going to use them.

They are free if you want them. They are super cheap at any radio shack also. I don't have the specs here at home but I do have them at work. I'll get the specs tomorrow and possibly the part number. Pm me for contacting me if you want the ones that came with my arc pig. I'm in the Chattanooga area
