I am using the foot pedal... The one that comes with the HTP is similar if not a rebadged SSC Controls pedal. I used the SSC pedal on my syncrowave but sold it with the machine. Really good quality pedal. Not using a hand control at all.

Not sure on the diameter but its something like 9' round....flange was cut back and we are re welding inside and out. 1/4 rolled gores and a 3 x 3 3/8 angle flange...good times out in the potash mines in Saskatchewan!

Lotsa room for air flow!

Yea i was thinking of that... We'll see how it works out ducting it shouldn't be needed... But if it is, well, i am a jm sheet metal guy shouldn't be too hard

And finished

And more....

I have had a syncrowave 200 for many years and strpped up to an inverter.... First thing is to get it off the bench! This is stuff i had laying around the yard and shop.

I have a tigerhood with the standard viewing size lense and an optel #10 ADF in it. I got that size cause most employers replace the standard plastics... I use it with a speedy loop for attatching to my fiber metal helmet and it works great, super light. Simplicity... Working out in Rocanville potas...
