Like:Hf start is reliable, spark gap comes pre-set and the unit appears to be tested and functions great out of the box.A minor nuisance is the "starting current" minimum appears to be 20A so although the arc starts without issue every time, you might struggle with very thin materials (razor blades, soda cans)Another minor nuisance is the "clean" setting as in "cleaning" or "penetration" or "ac balance" setting is in terms of Electrode Positive i.e. 5%-50%. Not bad per se just remember to calculate the inverse if you're copying settings from the internet. 65% on someone else's machine would be 35% on this machine. This is probably obvious but just subtract the number from 100 should get you pretty close.Sometimes the amperage output can be a little weird. The display will indicate 5A current but it seems like the current output decreases slightly after increasing the current while welding. Sometimes the machine seems to be delivering less current than the display indicates. This could be a combination of things. Technique, particularly the distance between the work and the tungsten electrode seems to lessen the impact quite a bit.Otherwise the machine is excellent so far, has been great with up to 14awg aluminum sheet on 120v input.Dislike:None of the included accessories were useful except the included gas hose and tig torch body.Accessory specifics:Handheld face shield isn't very useful for tig welding, maybe stick. It and the wire brush are standard accessories that are usually included with welders but you're probably going to want to buy an auto-dark helmet and a decent set of wire brushes.Argon regulator was good quality but has Cga-320 fitting. Will not fit a standard CGA-580 gas bottle fitting. You would need to purchase a Cga-580 To Cga-320 Adapter unless your bottle has that fitting. Maybe I'm in the minority but I've never seen that fitting on argon welding bottles.Tig torch is a standard WP-26 torch.Mine came with a #6 cup and 3/32 collet installed. Tung
