D/F Water-Cooled MIG Pistol - Pushing Aluminum

D/F PistolWith more than 44 years of welding experience, the D/F Machine Specialties Water-Cooled Semi Automatic MIG Pistol Grip Gun Model NC-21/HT-21 has proven itself continuously throughout its life, particularly in push welding aluminum trailers. The D/F Pistol is ideal for pushing 3/64", 1/16" and 3/32" aluminum wire up to 15' from the drive roll stand. It is built for use with all wire feeders that have a provision for water-cooling, and will handle all types of wire from .035" through 1/8" diameter. Because of its quality and durability, the D/F Pistol will last years and years vs. months, and will outlast any push-pull gun on the market at 1/2-1/3 of the cost. Maintenance is made easy with the D/F Pistol because of its few parts and simple maintenance.

Trailer Manufacturing
When manufacturing high quality aluminum trailers, it is important to consider longevity and strength of the weld joints. With aluminum in particular, it is somewhat of a fine-tune process to get a weld that will penetrate correctly with slightly higher heat and slightly lower travel speed. Also, choosing the correct wire size is crucial to an optimally strong aluminum weld. Since the D/F Water-Cooled Pistol Gun can handle a wide range of wires, and can hook up to any power source and wire feeder to accept any necessary welding parameters, it is a superior choice for manual MIG aluminum welding and trailer manufacturing.

Pushing Aluminum Wire
Feeding aluminum wire through a push only system is very advantageous. Because push-only guns like D/F Pistol Gun can hook up to any manufacturer's wire feeder and power source, large 500 lb spools of wire can be used reducing expenses, down time, and wear and tear on the torch by the changing of spools as in a spool gun. A spool gun needs to have the roll changed after every pound of wire is used, compared to the large size spools used in a D/F Pistol Gun. Also, the chance of burn-back exists when the end of a spool is reached, so many operators stop when a few turns are left on the spool.

Push Welding vs. Push-Pull Welding
A push gun also has advantages over a push-pull gun for many reasons. Typically, the greatest disadvantage of moving wire over long distances with a push-pull system is that it requires the most number of components and is the most expensive. It is very easy to mount a D/F Pistol Gun on a boom system to take all of the weight off of the gun. By mounting the wire feeder and power source on a 4-wheel cart, you can now travel great distances very easily. Push-pull guns are also very fragile and do not last as long (months vs. years). Push-pull guns are 2-3 times more expensive than the D/F Pistol. They only last up to 9 months on average, and you either have to replace the torch or rebuild by installing a new motor costing as much as $400-plus. Lastly but most importantly, because the D/F Pistol uses a 4" contact tip that is recessed in the water-cooling, not only is the arc stability increased, the tip life is increased 7-1, and there is built-in wire straightening. If the operator is using several pounds of aluminum per day, the few minutes need to change spools or replace motors can add up.
