You do need at least two batteries, as a single 12-volter won't supply enough power. A paired 12-volt and a 6-volt is the starting point, with two 12-volters generally working just fine once you learn a few tricks like proper wire size, wire stick-out length from the tip, and feed speed. The first thing I did was blow holes in ¼-inch plate, but after a few minutes of practice I was able to make welds equal to those of my high-dollar 220-volt machine. The welder also, has a stitch mode that enables you to weld 22-gauge with .023 wire and gas without blowing a hole at 24 VDC.

For batteries, I pulled one from my camper and the other, from my Jeep and hooked them positive to negative for 24 volts. OK, big question: How long will the batteries last? The manufacturer tells me that two premium deep-cycle 27-series batteries will provide four hours of intermittent weld time in the ideal situation. At, let's say, a foot of bead per minute on 3/16-inch material with some rest time between passes - well, you do the math (OK, I'll help):
60 minutes x 4 hours = 240 x 1 foot per minute = 240 feet of weld. However, 60 feet is probably more realistic.

 


The trigger control, nozzle tip, wire-speed control, drive motor, and wire spool are all housed in the hand-held gun unit.

While the Welder doesn't have a specific method of voltage control, you can vary the current somewhat by adjusting wire stick-out length and feed rate. In fact, one method is to use a 6-volt battery instead of a second or third 12-volt battery. There's also the option of a somewhat expensive but quality resistor pack available. I figured I would be smart and hooked up 40 feet of welding cable to use as a resistor. Wrong! I couldn't tell any difference. In fact, 25- or 50-foot extension cables are available.

 


We used two 12-volt batteries for our testing. We hooked them up in series to produce 24 volts, duplicating what we might use on the trail.

But by switching a Premier Power Welder control box over to the weld mode, you can clamp the Welder leads to the Premier welding cables and then adjust the engine rpm to match the welding voltage you need. I tried it with the leads in a straight polarity setting (electrode negative), the master and booster setting on, and about 36 volts registered on the gauge at idle. When welding, this dropped to about 18 volts. Playing with the throttle setting gave me a wide range of welding capacity as long as I didn't exceed 36 volts to the welder itself. The biggest drawback to this is you cannot weld on your own vehicle. Try it and you'll damage your Premiere Power unit.

 

In spite of that however, I'm beginning to wonder if I really need my big welder in the shop. The Welder is that versatile.



Welding with flux-core wire produces more sparks than with gas, and also some splatter and a cloud. But it still delivers very acceptable welds.

The upper pass shown here was made with an argon/CO2 gas mixture, the lower one with flux-core wire. Both are very acceptable welds on 1/4-inch steel.

As we said, the Welder II is a MIG or metal inert gas welder. This means the unit will weld with a cover gas shield if necessary. For welding aluminum, this is a must, and on steel, the weld is much cleaner. The trouble is that sometimes the wind is blowing and you'll find the cover gas isn't sticking around the weld site long enough to do its job. For these times, you can use a flux core wire. Flux core wire is the wire feed that is equivalent to a stick-welding rod. The weld will be covered with a flux coating that needs to be chipped off before the next weld pass. Since carrying a gas bottle just for your welder is a huge waste of space in a trail rig, you may want to plan to use flux core wire on the trail as a matter of course. With welding aluminum, you have two options. The first is to buy flux core aluminum wire, and the second is to use a cover gas. On the trail, this could be the CO2 in your Advanced Air System Power Tank. If you carry a PowerTank for filling tires and running power tools, don't overlook the fact that CO2 makes a fair cover gas for welding aluminum. Now all you have to do is block the wind.

We welded a few passes with a  Welder II running off a pair of batteries. After a few adjustments to the wire speed and our welding speed, we were able to produce a darn good-looking bead. We found the  Welder II to be easy to use and quite well built. The  Welder II is the perfect trail tool for repairs that require welding. In fact, it welds so well, you may find yourself using it at home as well as on the trail.

 


Weld Times

While length of weld time from a given pair of twelve volt batteries, wired in series, will vary with battery size, type and brand, amperage utilized to weld, % of full charge at which welding began, and other variables, such as ambient temperature, the following should provide an indication of battery life, from which weld times with alternatve batteries and under varying conditions can be estimated:

Two (2) deep cycle garden tractor/wheel chair type batteries (Type U1) were fully charged. We welded 30 seconds followed by a 90 second OFF period on 3/16" thick mild steel material with .030" Dia. Shelf-shielding electrode (gas-less) at an average of approximately 100 amps. Total weld time (not elapsed time) was 13 minutes for a bead of 13 feet. (Approximately a six (6) inch bead was welded during each 30 second weld period cycle.)
