The Power of Blue®.

Infinite current control allows the operator to adjust output by as little as

1-amp increments. Users can always get the exact heat they need, unlike the step control design on competitive products.

High 100% duty cycle rating:

100 amps AC/65 amps DC for the 225 AC/150 DC amp model. 130 amps AC/90 amps DC for the 300 AC/200 DC amp model.

The exclusive patented Accu-Set™ provides precise heat control with infinite amperage control.

High DC weld output: up to 150 amps for the 225 AC/150 DC model, and up to 200 amps for the 300 AC/200 DC model, available at 20% duty cycle. Thunderbolt XL 225 AC/150 DC model has 20% more DC output than competitive products.

Comes Complete With:

Power source with 15 ft (4.5 m) electrode cable, electrode holder, 10 ft (3 m) work cable with clamp, and power cord (without plug).

Note: Thunderbolt XL 225 AC/150 DC (#903 642) includes 230 V plug. Models do not include wall receptacle.

Output selector switch allows you to quickly select AC, DCEP or DCEN without adjusting the output leads.

Fully varnished magnetic coils: varnish protects and lengthens the life of the coils inside.

Forced-draft cooling fan runs continuously and helps to extend the life of the power source.
