Adjustable amps at the GTAW torch
Adjustable amps at the GTAW torch
(OP)
Is there a tig torch with variable amps adjustment 'on the fly'? I'd be interested in your thoughts if you have used them. I'd like something small and compact for sub 70amps work, mostly steel and stainless. I dont care for pedals at all.

For torches, I'd highly reccommend the Weldcraft line. The WP-24W is about as compact as you can get for a typical water-cooled offering. If you want something exceptionally compact, look at the WP-125 line. You can get standard and extended neck versions. They're designed originally for close quarters welding, i.e. tubing ID's, but we've used it successfully in narrow groove applications over 4" wall thickness. The OD of the cup is under 1/2" diameter.
I'd personally suggest the use of the thumb slider amptrols in lieu of the rotary ones on thin material. Nothing worse than coming to the end of a joint and not being able to back the heat off quickly enough, only to blow through.
Be sure to note also that you will only be able to use lift-arc or scratch start with the amptrols and may need a torch with a gas valve on it.

I hould rather have no remote than one attached to the torch. I have operated footpedals with elbows, kness, feet etc.. Anything but the TORCH hand.
For arounjd the house welding on a tabletop. It may be ok. But for anything else, scratch and go.
