Thank you for purchasing an HTP® Pro Pulse™ 300—our advanced, full synergic, multi-process welder. Our feature-
rich, high-quality, and versatile Pro Pulse 300 includes a pulse option in every welding process the machine offers;
welding processes offered by the Pro Pulse 300 include: SMAW (Stick), SMAW-P (pulsed Stick), GTAW (TIG), GTAW
-P (pulsed TIG), GMAW (MIG), and GMAW-P (pulsed MIG). In MIG mode, every pulse program, in every alloy and
every wire diameter, automatically includes options for standard double pulse and manual adjustable double pulse! These
features give you 100% control over the bead appearance and heat input at any given time.
The Pro Pulse 300 also offers the ability to run on single- or 3-phase power from 200V to 575V. Due to the extensive list
of accessories available for the Pro Pulse 300, the Pro Pulse 300 manual only describes the power source’s features and
capabilities; you can find more in-depth information on the use of accessories in their respective manuals (e.g., spool gun,
push-pull gun, TIG setup, or advanced MIG setup, etc.).
Please refer to the following list for accessories currently available for the Pro Pulse 300:
 10’, 12’, and 15’ air-cooled MIG welding guns for steel, stainless steel, silicon bronze, and flux-cored wires.

8’, 10’, and 12’ air-cooled MIG welding guns for aluminum wire.

10’ water-cooled MIG welding gun for aluminum wire.

Air-cooled and/or water-cooled specialty MIG welding guns for specialty applications and severe conditions
(available by special order).

19’ to 39’ air-cooled and/or water-cooled push-pull guns (we stock a 26’ water-cooled push-pull gun with built-in
remote control; all other options available by special order).
 25’ air-cooled spool guns (optional 50’ air-cooled and 25’ water-cooled spool guns available by special order).

12’ and 25’ air– and water-cooled TIG welding torches.

250A Stick welding electrode holder.

Smart water-cooler that controls the welding machine (if the cooler detects an issue, the cooler turns the welding
output off to protect your equipment).

Classic water-coolers with audible and visual flow alarms.
 Carts, flow meters, heavy-duty ground clamps, power plugs, etc.
In order for you to get the most out of your Pro Pulse 300, please work with HTP America, Inc. so we can help you
customize your Pro Pulse 300 package for your specific welding application(s)—communication is essential for us to
understand your needs and wants, as well as the task(s) you expect the Pro Pulse 300 to perform. For example, a customer
who builds aluminum trailers in a shop all day, and a customer who repairs those same trailers in the field all day, most
likely need the machine set up differently. If you then add assorted materials, material thicknesses, and multiple welding
processes into the mix, your package necessities become even more complicated.
The Pro Pulse 300 produces high-quality, virtually spatter-free welds on all common metals when you use the correct gas
and consumables for your welding application. By following the instructions closely, you can achieve success when
welding with the Pro Pulse 300, even when welding aluminum where the margin of error is very small. When welding
aluminum, almost everything must work out just right in order to achieve good results; without everything working out
just right, failure is likely. This does not mean that a novice welder will not be able to perform aluminum welds
successfully with the Pro Pulse 300. No matter your skill level, your chances of success dramatically increase with the
more knowledge you have about the welding process you plan to perform and the operation of the Pro Pulse 300. HTP
provides the Pro Pulse 300 manual and a few videos, along with classes at our Elk Grove Village, IL facility or on-site at
your facility, to familiarize you with, and help you weld successfully with, the Pro Pulse 300.
Customers interested in the Pro Pulse 300 often ask us the following questions:
If I buy the Pro Pulse 300, will I be able
to weld aluminum right out of the box? and Why do some customers find welding with the Pro Pulse 300 difficult? Why
do some customers, including customers with decades of regular MIG welding experience, struggle when welding with
the Pro Pulse 300 even after reading the entire manual twice and watching several videos?
First, the majority of our
customers successfully weld aluminum with the Pro Pulse 300 within hours, not days. Second, experienced welders
struggle when welding with the Pro Pulse 300 for multiple reasons, including the following:
