What does Tig rating 20 amps mean, does it mean you can't weld at a higher amperage than 20 with a tig ?

It means that the auto-on feature may not work if you are welding with less than 20 amps with TIG, not enough arc to actuate the sensor. I've welded some pretty lite material and the helmet always worked flawlessly. Helmet is worth every penny.

You can't tig weld aluminum on this machine. It does not have HF ac output. It weld stainless as good as any I've used. No foot pedal of coarse, but still welds great.

I use it for my welder and matched all specifications.You need to compare the wire sizing to amperage

its a great welder. i mainly run it on 220volts. just welded up my frame and made hardcore plate bumper. very strong. i also had to make floor pans out of 18 gauge. the original pans were probably only 22 and some spots kinda thin. it did very well. half way through i ran out of wire and had to use 0.35 flux and still performed well. the settings are fine and honestly only use three of them one for thin another for exhaust and than all the way with thick. i mainly change the wire speed. i have ran at max for probably too long many times and no problems. only tricky thing was first setting up wire tension. now it never jams. overall love it its a great welder. i mainly run it on 220volts. just welded up my frame and made hardcore plate bumper. very strong. i also had to make floor pans out of 18 gauge. the original pans were probably only 22 and some spots kinda thin. it did very well. half way through i ran out of wire and had to use 0.35 flux and still performed well. the settings are fine and honestly only use three of them one for thin another for exhaust and than all the way with thick. i mainly change the wire speed. i have ran at max for probably too long many times and no problems. only tricky thing was first setting... » Read More its a great welder. i mainly run it on 220volts. just welded up my frame and made hardcore plate bumper. very strong. i also had to make floor pans out of 18 gauge. the original pans were probably only 22 and some spots kinda thin. it did very well. half way through i ran out of wire and had to use 0.35 flux and still performed well. the settings are fine and honestly only use three of them one for thin another for exhaust and than all the way with thick. i mainly change the wire speed. i have ran at max for probably too long many times and no problems. only tricky thing was first setting up wire tension. now it never jams. overall love it « Show Less

My unit came through dual voltage and I can't see any difference when I'm welding except for max output being lower. I love my unit. Paul M

how thin of sheet metal will the tig weld. just learning to do tig welding do auto restoration work

The amp rating is for the jaws only. NEC table 310-16 shows that 1awg wire will do a max of 150 amps, and even professional rated welding cable at 1awg will only handle about 190 amps. The highest rated consumer available wire I've seen is 750MCM wire, which is over 1.15" in diameter, not nearly flexible or light enough for jumper cable use, and is still only rated at 535 amps.

The majority of an AVERAGE household's high-amperage draw items (air conditioner, washer, dryer, refrigerator, portable heater, hair dryers, microwaves, toasters) do not draw more than 15 amps. That has been the standard for all the houses I have been in. Yes, there are items you *might* need 20 amp service for, but they would be the exception to the normal.

Try switching your positive and negative wires, reverse em. I also immediately noticed you can weld with a bigger rod than they say with ease

If this is arc welding, then a higher voltage would allow a smaller tip. Most laboratory power supplies have a current limiting setting (left set of knobs). When operating in constant current mode, the supply will adjust it's voltage to whatever is needed to maintain that current. If that voltage is close to zero (due to short circuit), the current will still flow at the limit setting. If you max out the current limit setting to 3A, and the resistance is not too low, the supply can offer up to 30 volts (90 Watts max).

From what I understand, the amp rating is based on the length of the cord. My assumption from that is that the connectors at both ends are rated accordingly. If I were the manufacturer, I wouldn't put 20 amp connectors on a 15 amp rated cord.

I believe 20 amp for the 120 volt side of the welder and I ran 50 amp for the 208-230 volt side.

If you are running with 220v input voltage you should be OK. For 1/8" material your amperage should be close to the 60% duty cycle rating or about 5-6 min of continuous welding which should be adequate for 20" weld length. If your time in-between welds is short however, that could be an issue over a long time of continuous welding. I assume there will be some repositioning and other breaks which will increase the welder rest time. I typically do not weld more than 4-8 in. at a time but have never had any duty cycle issues. If you are using the 110v input you could run into problems with duty cycle as you are highly stressing the machine running 20" beads. If you are running with 220v input voltage you should be OK.

20 Amps is a max load for a 12-3 and if your going over a long distance the resistance will increase more. If it's new installation I would use 10-3 and then not have to worry. The cost difference is small.

On 120v a 20a dedicated circuit would be fine. On 220v it only draws 11amps I think, so 15-20 amp circuit. But keep in mind you get full output with 220 volt circuit too. I have tig welded on a 20amp 120v circuit with this thing with great results.

Checking amperage has safety implications, and I suspect that's why low-cost units are limited to 20A. You can get more information from the following video: http://m.youtube.com/watch?v=ar7qkMHKw4

20 amp for 110 and a 30 amp for 220 ... Only time ur gonna need 220 volts would b to weld Aluminum... Duty cycle is better on 110 also !! Machine works great .
