The stl is lift arc only,Both sth models do hf start from what I read.
Hf is only for the tig process.Can you use HF start when stick welding?
Do you mean in general or just for that machine?Hf is only for the tig process.
The op asked about the sth and sth L. Both do hf start from what I read. He did not as about the Stl I don't think.The stl is lift arc only,
The sth does both lift and hf start.
I missed the bit from the op with the letter L,The op asked about the sth and sth L. Both do hf start from what I read. He did not as about the Stl I don't think.
Never tried it?Do you mean in general or just for that machine?
What would happen if you tried stick in tig mode?
I tried to try it but I don't have a real stick electrode holder and my stick electrodes are too small for my tig torch collet.Never tried it?
Never tried it but rumour has it that the HF might/can/will leave the electrode randomly/sideways and take a chunk of the flux with it IIRC. It's not only the on/off switch that's bypassed when in stick mode, the volt-amp relationship typically changes too and/or the arc force control is activated which lets the user tweak the volt-amp curve.

What about the old Hitachi inverter pair or it's sister the Panasonic wx4? Or did they use something like 'mix TIG' rather than fully asymmetric AC?Miller was first with that. Asymmetric AC on the Aerowave, in the late 90s I think.
Most if not all inverters in the output range you've been looking at. My 200A Lincoln is happy enough running flat out from a 13A plug with everything turned upto 11 on AC TIG. It's supposed to be on a 16A 'slow' fuse (type C breaker, explained here http://www.neweysonline.co.uk/MCBs/Static.raction although it's happy enough with type B) and probably needs one for stick* if cranked up but with TIG it'll only pop the fuse in a 13A plug if using daft amounts of extension lead (voltage drop)So not to be whiny but, what machines work on 16A
What's that? I think it was it on the kempii website too.'mix TIG'
Advantage 18: MACS-procedure for thin aluminium sheets (AC/DC-model):
The MACS procedure (= Modulated AC system) from LORCH is a selective mixture of alternating current and direct current welding. Depending if the direct current phase is applied at the minus or plus polarity, it results in different cleaning efficiency, electrode temperatures and controls the welding result: Broad welding seam, little penetration (with MACS+) or narrow welding seam, deep penetration (with MACS).
I think you must have the sth L if yours dose stick to 150a.I missed the bit from the op with the letter L,
Didn't know there was an sth L?
Only stl (lift only) and sth (lift and hf) that i know of?
The murex/stel acdc 201 is rated to a 16amp slow on Tig and a 32amp supply for stick but Tig Paul runs this unit with no issues in his workshop from a domestic 13amp plugHmm, I'm thinking I might just pull the trigger and get the Miller 160 STH and return it if my breakers trip... Might be able to borrow some argon too. I contacted several forums about the 35A breaker Miller advices but they say "if it come with a standard plug, it's 16A max". I have pictures of the Miller with a standard EU plug so I might roll the dice....
I have the Stel version of this, It runs just fine from a 13 amp socket even flat out on AC tig, the mains cable is very thick and too big for a 13 amp plug so I have it wired on a 13 amp plug to 16 amp socket adaptor lead,
Matt I know you won't get a new murex stel machine they have not been made for some years. I was trying to explain that he should not be worrying too much about input supply as other, older, higher powered inverters cope well on domestic supply's even though they are rated higher. The murex was my example.He won't be able to buy a new Stel/Murex as it's not been made for years, might well pick a second hand unit up though.
Hotrodder, I think other people had this MACS/Hybrid/Mixed arc for a long time but it was Miller who was actually able to vary the current independently between the +\~ cycle. Everyone else had to be the same current on +\~ as whatever the main welding current was, although the patent for that run out years back as in sure Miller had it in the late 90's early 00's. I think as your only allowed 10 yrs without no one else using the same idea without your permission and paying a licence/royalty.
