WHAT YOU NEED TO OPERATE THIS MACHINE?

 

 

A properly grounded 110-120 VAC 50/60 hz. Circuit or a 220-240 VAC 50/60 hz. 30-50 amp 

Circuit. 

Remember: Machine must be grounded to work properly and safely!   

 

A clean and well-ventilated working place 

 

Heavy Duty Welding Gloves 

 

An Auto-Darkening Welding Mask to provide eye protection 

 

A compressed gas cylinder containing pure Argon 

 

Stainless steel wire welding brushes for each material to be welded 

 

A stone grinding wheel or a Tungsten Sharpener to sharpen the tungsten electrode 

 

 

Control Panel Information

 

1.

 

Power switch 1 is located on the back of the machine.     

2.

 

Downslope  adjustment  knob  2:  In  order  to  reduce  the  current  gradually  before  the  welding 

stops.   

a.

 

This knob is to adjust the current descending time.   

b.

 

Note:  If  you  are  using  the  “foot  pedal”  control;  you  should  turn  this  knob 

counter-clockwise to “0”.   

3.

 

Post-flow time adjustment (knob 3): To prevent the work piece from becoming oxidized, let 

the argon flow for few seconds after stopping the welding arc. This knob is for adjusting the 

post-flow time.   

4.

 

Foot  pedal  switch  4:  When  the  switch  is  on  the  “OFF”  position,  the  current  is  adjusted  by 
using  the  Current  adjustment  knob  5;  when  it  is  on  the  “PEDAL”  position,  the  current  is 

adjusted dynamically by foot pedal.   

5.

 

Current adjustment knob 5. Note: it only works when switch 4 (pedal/off) is on the “OFF” 

position. If switch 4 is set on the “PEDAL” mode, the current would be fully controlled by 

using the foot pedal instead.     

6.

 

Pulse  duty  knob  6:  During  AC  aluminum  Tig  welding,  Note:  For  an  increased  welding 

voltage of more than 150A, use pulse duty below 30% (or less than -1). For medium voltage 

(from 100A to 150A), use pulse 50% (0 on knob); For voltages less than 100A, use pulse duty 

more than 50% (+1 to +5).   

7.

 

Pre-flow time adjustment (knob 7): For better welding results, argon gas should come earlier 

than the current. This knob is to adjust the time between argon start and electric arc start.   

8.

 

Stick welding/Tig Welding Switch 8. For Tig welding, please switch to “Tig Mode”, For Stick 

Welding, please switch to “MMA mode”.       

9.

 

AC/DC Switch 9: For Aluminum welding, please switch to AC, for non-aluminum welding, 

please switch to DC.     

  

 

Overheat protection indicator (OC light): This is to protect the machine if it overheats. If the light is 

on, please stop the machine for 4 to 10 minutes before turning it on again.
