Yes that sounds like it's conected wrong in the picture I posted you con we the torc conected to just that one conection its a gas and power conection it'll probably be 3/8 bsp if you get it conected like I say I'm going positive you'll get hf how you have it conected will only scratch start because you've got it conected to the mma side of itJlg: Pretty sure I got it connected right I get an arc when touching the metal, but not by the HF spark itself.
Can you post a picture of how it's setupTIG: I connect the (gnd) clamp to the DCEP (+) out (in the middle and empty in the picture you posted). Torch is connected to the gas outlet which is also ground (upper left in your pic), and hf switch from torch right next to that again (like in your pic). Also the tig/mma selecting switch is in the left/tig position like in the picture.
When going MMA I move the tig/mma selecting switch to right/stick position, put gnd clamp in DCEN (-), and electrode/stick holder to DCEP (+).
Take a pic of the other side of the unit (black box).
