So, I have read just about every post on the forum, including a couple regarding torch sizes. I have to say, I thought you guys were full of it, talking about how much better it was using a smaller torch, and the benefits of using a smaller torch if the job and current required fall within torch spe...

I just realized, I used to have this issue on Ally, but I haven't in months. The only thing I switched is my tungsten from using a Green to a Blue. Are you by chance also using 100% tungsten? Hi cj737 I currently use a 3/32" 2% Thoriated Tungsten for steel work, and a 3/32" 0.8% Zirconate...

Most of the import machines I've used had this arc start issue & as others have said grounding the tungsten & retrying usually solves it ( I don't understand why - I have one that will maintain over an inch of arc length on HF but still can mess about initially ! no idea why )- though AC is...

I have a Sync 250 and have the same experience to report as Louie above. Not sure what causes it, the moon phase, the tide stage, the alignment of the planets or the activity of the sun spots, but I also ground the tungsten before starting and tell myself that makes it more reliable. FWIW, the manu...

I have the same problem on my Syncrowave. Its probably not the machine. I have heard lots of other folks complain about it. It seems to be a fairly common issue across a number of manufacturers and across both transformer machines and inverters. I just live with it personally. I routinely swipe the...

Hi cj737 Thanks for the reply. OK, I will try the more "aggressive" approach on the arc start, to see if it works. Now that you mention it, this problem does seem to occur if the tungsten has a bit of surface mill scale contamination on it from mild steel work. Probably the same holds true...

Hi from a loooong time lurker ;) Some assistance would be much appreciated. When I Tig weld on either AC or DC, the HF start can be intermittent. Sometimes the arc initiates perfectly, other times not at all. In the instances when the arc does not strike, I have found that letting off the pedal comp...

Hi I have the same welder (different name brand, but the same machine) and am very keen to find out how you change the output AC frequency from the standard fixed 60Hz. Am I correct in understanding your post that you have modified the machine to be able to change the AC output frequency, independen...
