Re: What watt is enough to run 200DX?

You also need to know the amps available on your generator if using 230v power. It's not just about the wattage... Striking the rod will draw the most amps but then settle in once lit. The higher amps your Dynasty is set to, the greater the wattage seen at the generator.

Re: I am having a hard time walking the cup.

In addition to Poland's comments, use a flexible head torch to get the shaft inline with your travel direction. And, walking the cup can become tricky on carbon steel once it gets really hot. This causes the cup to get "sticky" against the metal and you have to jam it, glide it, jam it... ...

Re: 1st tig weld, I think there is hope

What you should notice is that about halfway through your bead runs, the heat accumulates in the base part, making the bead begin to get "grainy" looking and flatter. That is when you need to back-off the pedal, or increase the tempo of rod and cup movement. Its a delicate balance of fille...

Re: 1st tig weld, I think there is hope

Some other tips with you Dynasty and thin aluminum is to set the pulse on. That turns the heat back and allows you to use more amps (probably 125) without over cooking the sheet while you trudge along. Also, try using 150hz and see if that doesn't produce a better looking result, and balance between...

Re: Argon / Helium Mix for Mig Aluminum

You can, but you might be trying to weld too thick a piece of aluminum on your 110v welder. Aluminum takes a lot of amperage. Can also preheat with propane as a test to see if that helps. What machine, amps and wire speed are you using? Material thickness and wire gauge?

Re: Aluminum Boat Transom Corrosion Repair

Most marine aluminum is 5xxx series, so easier to weld with 5xxx rod (and cheaper). I literally just did a transom extension on a Jon boat 2 weeks ago, and encountered some of these issues. You can, plate either side and weld the panel to the transom. You can back either side with copper as suggeste...

Re: Buying a new Air compressor

Even if you have separators, the routing of the plumbing can produce worse/better results. Best to have your service lines running above the separator, and the filters/separators plumbed in low (gravity draws moisture down). If your tank is rusting, consider its location; indoors or outdoors? Is you...

Re: the million dollar question !!!

When you initiate the AC arc, it will wander until you get it cranked up and stabilized. Either more pedal faster, or wait until it stabilizes to before you panic. A "steep angle" is the cup as close as perpendicular to the line of the surface (to be clear). When you lay the cup back, in a...

Re: Inside corner weld tips(aluminum)

A "flatter" bead can be accomplished in a number of ways: less filler rod, travel further between dips, different AC balance, smaller wire, burning in longer before travel, etc... From your description, it sounds like your amps are low and rod is thick. You might experiment with higher amp...

Re: GTAW on 16 gauge steel exhaust manifold

I'll offer you some opinion and advice based upon observations: Amps needed will be low. I just welded 16 gauge sheet yesterday and used between 20-40 amps on my foot pedal. I used a 3/32 tungsten with about 13-15cfh, postflow of about 8.5 seconds (more than needed). Your objective is dicey. To buil...

Re: New to Welding!

You didn't mention what machine you're welding with either. Depending upon the box, changing the frequency or AC Balance can effect your welds quite a bit too. Also, on thin tubing, setting the background pulse helps a lot to prevent blowout. When you weld aluminum, it takes a bit of time for the fi...

Re: Which filler rod to TIG weld this old motorcycle frame.

I do a fair bit of work on vintage bikes and always use 70-S2, straight argon, and a 3/32 tungsten. The tubing is pretty darn thin, so watch your heat and use a 1/16 wire if the area is narrow enough. Using a pedal, I probably end up applying about 25-40 amps maximum.

Re: What TIG welder is good for a beginner

To find a decent AC/DC TIG box, you'll spend some money. the Lincoln Squarewave 200 is a very good value, and it does have HF start. For DC only, you can spend less, but no aluminum and you may end up with a "Lift Arc" or "Scratch Start" only TIG. Not the best for "art"...

Re: Lincoln SW 200 Purchase Questions

Just some friendly input about pre-set PostFlow. Even if you installed an inline solenoid, the gas is already released from the tank into the line. So, whether you use a solenoid or a manual gas valve torch, the moment you open the valve, the accumulated gas will flow out. You can consider it a pre-...
