Maxstar 175 single phase conversion

[mater365]

I know there is a bit of info out on the internet about converting a 175 to single phase and it basically becomes a 152. I have attempted to follow one instruction to convert my machine but have run into a problem. The post is fuzzy on the last crucial step and picture attached which leaves me scratching my head. I have converted my welder but something is wrong and I barely have any power at wide open amp. The instruction states that the transformer for the fan also feeds the power board. I believe this is where the problem lies. Has anyone had success with this? If so I could use your help.

Have you had any luck with this issue?

No resolution.Need an electronics background to interpret the schematic.

You'd have to move your fan/supply transformer input to L2, but looks like thats about it, other than not using the red input wire

The fan worked fine. The problem is the board isn't getting full power. The machined worked fine when converted back the 3 phase.
