Thread: TIG Welders

Hello,
The 4 way switch is a trigger lock one touch on, touch again off, you do not hav eto keep holding it on. 2 way is holding it on to keep welding.
There are lots of trick to welding panel steel to keep distortion down is as soon as you have finished welding put a wet cloth on it as soon as possible you can use silicon bronze rods a little less heat. Me with panel steel I use my MIG and spot it ( pull trigger a second then release) then no distortion at all especially on holes like you have.

Depending on the unit you have with the 2T and 4T settings for the torch trigger there are a few added bonuses like hot start or slope up at the start and crater fill or slope down st the end of the run

I use a trans tig 200 ac/dc unit it has all the bells and bits and using it on ally i use the 4T function as follows
Push and hold button down i get a hot start i usually set at 30% more than base amps
Release trigger slopes back to set base amps which i can now control at the tip of my finger via a roller control in the torch whilst laying my weld as this is great for ally as it heats the job up less amps are needed
Push and hold trigger for slope down and ad a bit of wire at the end so i get a nice rounded off weld finish instead of a scalped out tail

As for pulse welding its a whole other art and once mastered you can time the dip of wire to the up slope of the pulse and get robot looking welds its amazing what you can do with a good tig and plenty of practice and patience
