found that some brands/models of auto-darkening welding helmets experience interference issues with the Pro Pulse
220 MTS. Since the frequency changes according to wire speed, we noticed that a wire speed adjustment of +/-20
IPM typically alleviates the issues. We also noticed that video cameras or security cameras within close proximity to
the Pro Pulse 220 MTS, when welding in a pulse program, show the interference in the recorded picture.
Although the spray arc itself is almost silent (just a slight hiss), the sound of the pulse is well noticeable. It sounds, at
times, much like an AC TIG welder. If you are used to the classic MIG frying bacon sound, the sounds the Pro Pulse
220 MTS makes will take a little adjustment time to get used to.
Welding guns compatible with the Pro Pulse 220 MTS include:
HTP 15 Series MIG Welding Gun
HTP 24 Series MIG Welding Gun
HTP 26 Series MIG Welding Gun
HTP RSG 250 PP220 Air-Cooled Spool Gun
HTP PPAC 6M 0.9 Air-Cooled Push/Pull Gun
Below, we discuss the capabilities and limitations of each of these guns.
HTP 15 Series MIG Welding Gun —The smallest of the guns. Excellent for reaching into tight spaces (e.g., work on
cars). Also, lightweight for less operator fatigue. Best for use on steel (non-pulse). Not suitable for pulse welding
steel, and limited potential for pulse welding silicon bronze in the collision repair industry. Although we also sell the
gun in 12’ and 15’ lengths, only the 10’ gun may be used when welding .023” diameter wire, and even larger
diameter wires will most likely NOT give you a trouble-free welding experience. We, therefore, recommend using
only a maximum gun length of 10’. If you require a longer gun, either upgrade to a push/pull system or to the Pro
Pulse 300, which features a different wire feed system.
HTP 24 Series MIG Welding Gun —Slightly larger than the 15 Series MIG Welding Gun. Still lightweight and fits
into most small spaces. For pulse welding, we recommend a maximum gun length of 10’. Although we also sell the
gun in 12’ and 15’ lengths, only the 10’ gun may be used when welding .023” diameter wire, and even larger
diameter wires will most likely NOT give you a trouble-free welding experience. We, therefore, recommend using
only a maximum gun length of 10’. If you require a longer gun, either upgrade to a push/pull system or to the Pro
Pulse 300, which features a different wire feed system. For any kind of pulse welding, long-life tips should be used.
Failure to do so will result in premature tip wear, poor weld quality, burn backs, birds nesting, and other problems.
The 24 Series MIG Welding Gun can be used for:
 Steel (all diameters and thicknesses; both pulse and non-pulse)
 Flux-cored (all thicknesses; with or without gas)

Stainless Steel and Silicon Bronze (all thicknesses)
HTP 26 Series MIG Welding Gun —Noticeably larger than the 24 Series MIG Welding Gun with a thicker torch
cable (the thicker torch cable helps the operator keep the gun straight, which is especially important when welding
aluminum). Comes in an 8’ length with M8 size long-life contact tips. The 26 Series MIG Welding Gun can be used
for:
 Aluminum (EVERY wire diameter from .030” to .047” (3/64”); EVERY alloy (4043, 5356, and 5554 namely))
The 26 Series MIG welding gun might also be used for:
 Steel (all diameters and thicknesses; both pulse and non-pulse)
 Flux-cored (all thicknesses; with and without gas)
 Stainless Steel and Silicon Bronze (all thicknesses)
In doing so, modifications to the gun must be made (a different liner must be installed), which essentially renders the
gun useless for aluminum. However, a modification like this may be a good choice if you require an extra heavy-duty
welding gun for high heat situations and if the 24 Series MIG welding gun does not provided sufficient performance.
