I finally got myself a DC Welder.
It's a Winner MMA-168
150A, 85% duty cycle.

Here is the website of the manufacturer. http://www.winnerwelding.com/product/prod-mma168.htm
It seems a decent company.

It is distributed locally by Premium Graphics Tarpaulin system, sales agent. Edward Sumile. They do not have dealers, they demo directly to end users especially to fabricators.

During the 1st demo, we tried cutting with 6013/ 1/8 rods without a hitch. However, their 4 yr old demo unit bogged down when we used 5/32s halfway thru a stick. Agent claimed the units cooling fan is defective.

The 2nd demo was 9am the next day, he brought a brand new unit, we tested 6013s, 1/8th rod on a piece of leaf spring flawlessly. This made me buy the machine.

Last night was the 3rd demo already for me.

I'm not a welder by any means, but the demo was seen by several guys during the EB JayL, Moji, Jadama, Komobi24, Chisel, Joey81 and Timber715. I will let them chime in on their impressions. We tested a few sticks of 6013, 1/8th rods.

The agent claims the machine will burn 10-100s 1/8th rods continuously, the downside is the machine as no overload protection. Once the OC Led lights up, you will need to bring the unit in for repairs as what happened during the 1st demo.

Price is 8.5k, but I think it can still be haggled down a bit. Pricier than one of our favorite, but here's some pics for you to judge.

Some more pics.

Electrode holder and ground clamps are decent enough. No upgrades for now.

Overall, I think this unit will suit my needs. The agent claims their other clients are using it for production/fabrication use, so this should be more than enough for me.

Now to get a decent helmet and some welding rods.

24" high platform for a 10 foot tarpaulin printer. Project is in Olongapo City, letting my wroker handle it. Let's see the abuse it can take.

I emailed the manufacturer in Taiwan asking about the OC indicator light. When the OC lights up and unit stop working, it should be able to restart again in several minutes.

You can ask joey81 or JAyL regarding the Yamato circuits. Especially Joey81, I think he has extensive experience on the Yamato PCBs already.

The foot print of that DC welder is smaller compared to other brands. Probably a factor to consider if you intend to do mobile works.

It does no seem to be from the pics but on actual side to side comparison it would be very noticeable.

Ernie I have not fully checked both welder's innards but from a quick look it's very noticeable that the Winner has more IGB Transistors.

Judging from the pics posted by BF this DC Welder has a clean build as well. It was sad we did not have any welding helmet available during the demo thus it was not tested properly by members who attended BF's EB.

As per supplier, the MMA168 is not using IGBTs, Mosfet most probably. From what I gathered, IGBTs should be better. At the end, its still the overall design and build that counts rather one specific technology. Too early to tell how the MMA168 will hold up, but 1 year full parts and service warranty is what convinced me, I just hope I wont need to avail of this.

Ernie, I can have the sales person sked you a demo if you want.
