Tweco SG200REB Spool Gun

This air-cooled MIG spool gun is built for welding aluminium with a 4 inch spool capacity. It delivers up to 200 A at a 60 percent duty cycle using argon shielding gas. The pistol-grip handle and micro-switch trigger provide control for MIG welding tasks. It connects via a Tweco-compatible rear connection.

Suits aluminium MIG work not heavy steel

Welders running aluminium wire up to .047 in diameter on a 25 ft cable will find this gun suitable. The fixed 180 degree neck and Tip Series 11 tips support consistent feeding. Buyers needing water cooling or higher amperage for thick steel fabrication should look elsewhere. It is not designed for flux-cored or stainless steel wire types.

200 A 60 % duty cycle decides fit

The maximum current of 200 A at 60 percent duty cycle is the key figure that determines if this gun matches your welder output. Exceeding this rating will overheat the air-cooled cable assembly. Verify your machine settings against this limit before purchase. The 25 ft length and rear connection must also match your setup.

Questions about this item

How often will the contact tip need replacement on this SG200REB-25-3545?

The gun uses Tip Series 11; tip life varies with wire feed speed and material but expect to change tips every few rolls of .047 in aluminium wire under normal use.

What limits continuous welding at the 200 A rating?

The 60 percent duty cycle at 200 A means you can weld for six minutes out of every ten before the air-cooled gun must cool down.

How hot or noisy does the gun get during all-day production runs?

Air cooling keeps the handle warm but manageable; the micro-switch trigger clicks quietly and the 25 ft cable stays flexible without excessive heat buildup.
