TIG issue
Posted: Fri Nov 03, 2017 3:59 am
Hi guys,
I'm relatively new to TIG welding. I weld flatware, bike chains etc into sculptures, so pretty thin metals. I use a Bossweld EVO 140, which means i need to scratch start.
I'm hoping someone can tell me what i'm doing wrong here (or if it's just an unavoidable issue). I find that the welding is hottest immediately it starts, and then cools down dramatically. So that means that if I either bump up the amperage (and risk doing damage at the beginning, but weld okay after initial overheat), or I stop and start welding so i continually have the higher tempreture. I'm not sure what I'm doing wrong? Why does it drop temp so quickly please?
Thanks for any ideas,
Todd
