Re: Miller XMT 350 HELP-3 while welding
Me too, maybe I need open up the case and blow the dust out? Definitely do that. If there's dust and debris caked on the components then it can't shed the heat and will thermally overload much sooner than expected. Also check that the intake and exhaust vents are not obstructed (eg. dirty filter if...

Re: new welder, why does my torch keep welding when I let o
It may default to 4T for the button control when set to 'panel'. 4T style would work like this: - Bring the torch to the workpiece - Click the button once and release it, arc initiates and will stay lit - Get your weld going... - Once you want to stop, click the button again, arc will taper off and ...

Re: TIG Welding 316 Stainless Steel
Yup.. LIke mentioned above you need to use at least 316 filler and usually pickle/passivate afterwards to get a 'pure' stainless surface again that can form it's protective oxide layer. But the issue with welding stainless is also in how hot you get the area around the weld. If you overheat the base...

Alu inside corners are often tricky for many people. Here Jody's mantra of 'keep a tight arc' and giving it enough amps really helps to get the job done. Bury that tungsten deep in the corner and hit that pedal. Difficulty here lies mostly in getting going smoothly. The initial puddle forming takes ...

Re: Overheating 6061 while tigging?
My main concern is if its possible or likely i’ll see a failure from overheating the part. For alloyed alu types like 6061 the most 'damage' you do by heating it a lot is that it can lose some of it's strength that was incorporated in the (usualy) T6 hardening. Of course the weld itself and HAZ are...

Re: Stainless steel color and quality
This question depends a lot on the type of stainless being welded. An austenitic stainless like 304/316 won't be affected much by the heat of the base metal and as long as you keep it covered in gas then the corrosion resistance should not be affected and neither will the grain structure. This type ...

Stitching might be an option, but here I think it's too close to the edge and the load from the fastener wanting to spread the crack open as the head is torqued down will overwhelm it.

I've done some plastic welding, it rarely works or I'm just bad at it. Plastic welding effectiveness is highly dependent on the base material though. Some plastics work a lot better when (re)heating and melting than others. All of them suffer from more or less work-hardening in the base material th...

That sounds wrong..
Regulator should not leak/vent any gas when in use, except out the bit where you want the gas to come from
Are the ports perhaps for gauge(s) or such?
